  Issue link: <http://db.tidbits.com/issue/966>

  There's an undercurrent of keeping your Mac safe throughout this 
  week's TidBITS issue. First, Adam passes on news of a critical 
  vulnerability in Adobe Reader and Acrobat, along with suggestions on 
  how to avoid being bitten by the current exploits. Jeff Carlson 
  points out that a part of anyone's backup strategy should be keeping 
  the power on, via a UPS. And Doug McLean shares details about the 
  liquid submersion indicators now built into all iPods, iPhones, and 
  MacBooks. But we're not going all paranoid on you - Adam also dives 
  deep into iPhoto '09 and returns with news that Apple seems to be 
  working on an iPhone application that tracks your location. Jeff 
  also explains how you can get a free Mac.com account for use with 
  iChat, since trial MobileMe accounts expire. And finally, Doug 
  contributes a roundup of his favorite screensavers that go beyond 
  bouncing a picture around your screen. We've also just published 
  "Take Control of Running Windows on a Mac, Third Edition," and our 
  Dutch and Japanese translations could use some more help. Notable 
  software releases this week include ScreenFlow 1.5, MercuryMover 
  2.0.3, TextExpander 2.5.2, MacBook SMC Update 1.3, WireTap Studio 
  1.0.8, Things 1.0.4, and the ConceptDraw WebWave plug-in for 
  ConceptDraw Pro.

Critical Vulnerability in Adobe Reader and Acrobat
--------------------------------------------------
  by Adam C. Engst <ace@tidbits.com>
  article link: <http://db.tidbits.com/article/10087>

  Adobe has issued a security advisory warning about a "critical 
  vulnerability" in all fully patched versions of Adobe Reader 9 and 
  earlier, and in Adobe Acrobat 9 and earlier. Although the security 
  advisory makes no specific mention of the Mac, previous 
  vulnerabilities have been cross-platform, so there's no reason to 
  believe this one will be any different. Adobe expects to issue an 
  update for the latest versions of Adobe Reader and Acrobat by 
  11-Mar-09.

<http://www.adobe.com/support/security/advisories/apsa09-01.html>

  Details of the vulnerability? A malicious PDF could cause the 
  affected application to crash and could potentially allow an 
  attacker to take control of the computer. I know that's what we 
  always say, but in this case, there are reports of this 
  vulnerability being exploited in the wild, at least in the Windows 
  world.

  Luckily, the security group Shadowserver has verified the exploit 
  with Adobe Reader 8 and 9 on Windows. Their posting explains that 
  the vulnerability relies in part on JavaScript, such that turning 
  off JavaScript is an easy way to mitigate the problem. In their 
  testing, a malicious PDF could still crash Adobe Reader if 
  JavaScript was turned off, but it couldn't take over the machine.

<http://www.shadowserver.org/wiki/pmwiki.php?n=Calendar.20090219>

  To disable JavaScript, deselect the Enable Acrobat JavaScript 
  checkbox in the JavaScript pane of Adobe Reader's and Acrobat's 
  preferences. 

<http://www.tidbits.com/resources/2009-02/JavaScript-setting.png>

  Since Apple's Preview and most, if not all, other Mac OS X PDF 
  readers cannot interpret JavaScript in a PDF, I suspect that they 
  would be unaffected by a malicious PDF. To change the default so all 
  PDFs open with Preview, choose File > Get Info (Command-I) for any 
  PDF, choose Preview from the Open With pop-up menu, and click the 
  Change All button.

<http://www.tidbits.com/resources/2009-02/Reset-PDF-Open-With-setting.png>

  It's distressing that Adobe's security advisory provides no 
  practical information that would help users protect themselves until 
  an update appears. Aside from the lack of platform-specific detail, 
  would it have killed Adobe to suggest that users turn off JavaScript 
  and avoid PDF files from dodgy sites?


iPhone to Add Location Logging?
-------------------------------
  by Adam C. Engst <ace@tidbits.com>
  article link: <http://db.tidbits.com/article/10083>

  Could the iPhone soon be able to track your location in the 
  background as you walk around? A hint that such a capability is in 
  the works at Apple comes from a programmer friend who spent some 
  time spelunking around inside iPhoto '09, which shows traces of 
  being able to associate such GPS log data with photos. 

  That could provide geotagging information for photos taken with 
  another camera, or it might let you view a map of your travels, with 
  pins dropped where you'd taken photos with the iPhone.

  My source points to an unused nib file within iPhoto as evidence of 
  this feature. As you can see from the screenshot and the text below, 
  it's assuming that there's a Location app on the iPhone, and that 
  app must be running to transfer location data to iPhoto.

<http://www.tidbits.com/resources/2009-02/PhoneLocationBrowser-nib.png>

    Activate the location application on your iPhone or iPod Touch. Once selected, any available location information will be transferred to your iPhoto library and associated with the photos in the selected event(s).

  Elsewhere, in the iPhoto binary, there's also this string, which 
  appears to provide the iPhoto side of the directions:

    Select an iPhone or iPod Touch from your list of named devices. Once selected, the appropriate information will be transferred to your iPhoto library and associated with the photos in the selected event(s).

  The user experience seems rather convoluted, since the implication 
  from these strings is that you would have to select one or more 
  events in iPhoto, then launch the app on the iPhone to transfer 
  location information via Wi-Fi. Quibbling with the interface is 
  pointless, though, given that this feature is non-functional in 
  iPhoto '09, and there's no known Location app in the iPhone with 
  which to connect. 

  Setting the speculation phasers on stun, therefore, ponder the 
  following:

* One of the issues with the iPhone is that independent apps can't 
  stay active in the background, so GPS-based apps must be onscreen at 
  all times to capture location data. Apple isn't subject to that 
  limitation, so a Location app from Apple could track location no 
  matter what you're doing. Apple should open that capability up to 
  developers as well.

* The text mentions the iPod touch, which is a bit odd. Although the 
  iPod touch can figure out its location from nearby Wi-Fi networks, 
  the feature is worthless if you're anywhere but a heavily built-up 
  urban area. And of course, the iPod touch currently has no GPS or 
  camera. Could that be changing in a future model?

* One problem with using the iPhone's GPS constantly is that it drains 
  the battery in just a couple of hours. I can't really see this 
  feature being useful unless the iPhone were to get better battery 
  life while using GPS. Or, I suppose, the Location app could rely 
  largely on cell phone tower triangulation (which I suspect works 
  better inside buildings anyway), using GPS occasionally to improve 
  accuracy when available.

* The text talks about the location data being associated with "the 
  photos in the selected event(s)." That could be interpreted to mean 
  that the Location app's data could be used to geotag photos from 
  non-GPS-capable cameras, much as you can do now with a GPS data 
  logger device and a program like HoudahGeo or Ovolab's Geophoto. 
  Since so few cameras offer GPS support right now, those programs 
  remain extremely useful for automatic addition of location 
  information.

<http://www.houdah.com/houdahGeo/>
<http://www.ovolab.com/geophoto/>

* iPhoto '09 can already show you a map containing your geotagged 
  photos from the iPhone, and it can show a path between photos within 
  a map in a book, but it's just drawing lines between photo locations 
  - it doesn't actually know the path you took between the points 
  where you took the photos. This feature could enhance such maps with 
  your actual path.

  In the end, there's no guarantee that Apple has done more than toyed 
  with the idea of garnering additional location-based data for 
  iPhoto's geotagging feature. Such a feature would need to be 
  designed and introduced extremely carefully, to ensure that users 
  had sufficient control over it to avoid privacy concerns, and to 
  ensure that the messaging around the app didn't give the wrong 
  impression. Given that many of the marketing blurbs for the GPS data 
  logging devices gleefully suggest privacy-infringing uses like 
  spying on a teenager, spouse, or employee, caution on Apple's part 
  seems entirely warranted.


Get a Free, Non-Expiring Mac.com Address for iChat
--------------------------------------------------
  by Jeff Carlson <jeffc@tidbits.com>
  article link: <http://db.tidbits.com/article/10084>

  A TidBITS reader writes:

    It seems that as part of the conversion from .Mac to MobileMe, Apple no longer allows expired MobileMe accounts to be used for iChat. My mother-in-law got a 60-day free MobileMe account solely for iChat purposes. As soon as she cancelled it (shortly before the free 60 days expired), she was no longer able to use iChat.

  It's true that a me.com address expires if you don't subscribe to 
  MobileMe within the free period. Apple is doing all it can to 
  encourage people to use the paid service. If you were a subscriber 
  to .Mac, the precursor to MobileMe, then you already have a mac.com 
  address that will work in the future, even if you opted to not renew 
  your .Mac/MobileMe account.

  However, you can also create a free mac.com address for use with 
  iChat that won't expire. It can be used only for iChat, and doesn't 
  include email or any of the other MobileMe features, including 
  encrypted iChat messaging.

  Here's how:

  1. In iChat, choose Preferences from the iChat menu.

  2. Click the Accounts icon at the top of the window.

  3. Click the + (plus) button in the lower-left corner to create a 
  new account.

  4. Click the Get an iChat Account button, which takes you to Apple's 
  site in your Web browser.

  5. Fill out the fields in the Create Your iChat ID form and click 
  Continue. If your chosen screen name is already taken, you'll need 
  to come up with a new one.

  6. Go back to iChat's preferences and choose Mac.com Account from 
  the Account Type pop-up menu.

<http://www.tidbits.com/resources/2009-02/ichat_dotmac_account.png>

  7. Enter your just-created user name and password in the fields 
  provided, then click Done.

  This technique is also helpful for creating extra iChat addresses; 
  for example, it can be handy for people who want to separate work 
  and personal chats. When the account is enabled, you'll see two AIM 
  Buddy Lists, which you can populate separately and run 
  simultaneously.


The Latest Details about Running Windows on a Mac
-------------------------------------------------
  by Adam C. Engst <ace@tidbits.com>
  article link: <http://db.tidbits.com/article/10085>

  Now that running Windows on a Mac has become commonplace, you might 
  think that it's also become easy. Alas, the gods of technology have 
  yet to make it so, and making Windows run smoothly can still make 
  you want to rip your hair out. Of course, this fact also keeps Mac 
  writers like Joe Kissell busy, and, taking advantage of Joe's 
  unstoppable curiosity, we've just released his latest ebook, "Take 
  Control of Running Windows on a Mac, Third Edition," with coverage 
  of the latest versions of VMware Fusion, Parallels Desktop, 
  VirtualBox, and Boot Camp.

<http://www.takecontrolbooks.com/windows-on-mac?pt=TB966>

  The 167-page ebook helps you figure out which virtualization 
  software makes sense for you, round up the necessary hardware and 
  software, make any obligatory preparations (like partitioning with 
  the right format - FAT32, anybody?), and get it all working right 
  with hardware drivers installed, printers printing, anti-virus 
  software patrolling the perimeter, and so forth. Joe also gets into 
  the details of sharing files between Mac and Windows installations, 
  making the most of the snazzy new features in the latest versions of 
  Parallels Desktop and VMware Fusion, creating functional backups of 
  your Windows installation, and generally getting on with your life 
  while using Windows. To make the $10 ebook even more valuable, it 
  comes with coupons for $8 off VMware Fusion and $5 off Parallels 
  Desktop.

  Since this book covers all the options for running Windows on a Mac, 
  those of you who are using or plan to use VMware Fusion will 
  probably be happier with Joe's "Take Control of VMware Fusion 2," 
  which is also available for $10 and which also comes with a coupon 
  worth $8 off the purchase price of Fusion.

<http://www.takecontrolbooks.com/vmware-fusion-2?pt=TB966>

  If you already own a previous edition of "Take Control of Running 
  Windows on a Mac," be sure to check your email for a discount update 
  offer, or find the update offer by opening the ebook and clicking 
  the Check for Updates button on the first page. 


More Dutch and Japanese Translators Wanted!
-------------------------------------------
  by Adam C. Engst <ace@tidbits.com>
  article link: <http://db.tidbits.com/article/10090>

  We're hard at work on bringing translations into our homegrown 
  TidBITS Publishing System as a way of making TidBITS even more 
  accessible to people who prefer to read in languages other than 
  English. But while we're enhancing our content management system, 
  our volunteer translators continue to put out issues of TidBITS each 
  week in other languages.

  So, if you're bilingual in English and either Dutch or Japanese (all 
  three is not required!), we can use your help. Both our Dutch and 
  Japanese translation teams are running slightly short-handed and 
  could use a few more volunteers to spread out the effort. In 
  essence, you'd work with the other members of the teams to help 
  translate TidBITS from English into either Dutch or Japanese for the 
  thousands of people who read TidBITS in those languages. 

  You can read more about what's involved with both the Dutch 
  translation and the Japanese translation at their respective pages. 
  Thanks for any help you can provide, and do note that as a small 
  token of our appreciation, translators receive all Take Control 
  ebooks for free.

Backups Need Power, Too
-----------------------
  by Jeff Carlson <jeffc@tidbits.com>
  article link: <http://db.tidbits.com/article/10086>

  After learning our lessons the hard way, we at TidBITS are adamant 
  about backing up our data and evangelizing the importance of having 
  good backups. (For examples, see Adam's article "International 
  Verify Your Backups Day," 2009-02-13, Joe's ebooks "Take Control of 
  Mac OS X Backups" and "Take Control of Easy Backups in Leopard," and 
  my own travails and successes recovering the contents of a failed 
  hard disk, "DriveSavers to the Rescue," 1999-08-30.)

<http://db.tidbits.com/article/10071>
<http://www.takecontrolbooks.com/backup-macosx?pt=966>
<http://www.takecontrolbooks.com/leopard-easy-backup?pt=966>
<http://db.tidbits.com/article/5530>

  But making copies of bits isn't the only consideration for keeping 
  your data intact. You need electricity to feed your computer and 
  hard drives - and that electricity needs to keep running, especially 
  in the event that the power goes out unexpectedly. An abrupt 
  shutdown can cause disk directory corruption, and power surges risk 
  overloading and damaging power supplies.

  I was reminded of these facts recently when I was interrupted by a 
  shrill and sudden beeping from beneath my desk. A dreaded red light 
  appeared on the UPS (uninterruptible power supply) into which my 
  computer and accessories are plugged, indicating that its battery 
  was dead.

  If you're not familiar with the device, a UPS is essentially a 
  multi-plug power strip with a built in battery that can keep 
  electricity flowing for several minutes in the event of a power 
  outage. It also provides protection from power surges and filters 
  the incoming power to reduce fluctuations. In my case, I was using 
  an old APC Smart-UPS 1000 I inherited from Glenn Fleishman when he 
  stopped running Web servers out of our shared office.

<http://www.apc.com/resource/include/techspec_index.cfm?base_sku=SU1000NET>

  The good thing about a UPS is that you can replace the battery 
  without replacing the whole unit. So I went to APC's Web site and 
  discovered that it would cost about $150 for a new battery.

  While browsing APC's other offerings I came across the company's 
  Trade-UPS program. APC will give you credit toward buying a new UPS, 
  and also recycle your old one and pay for the shipping. The last 
  item is significant, since UPSes are quite heavy (the Smart-UPS 1000 
  weighs 46 pounds).

<http://buy.apc.com/commerce/storefronts/tradeups/tradein.aspx>

  I entered my UPS and its serial number in the Trade-UPS page, which 
  gave me a point value of 1000; I would need to match that number in 
  new products to qualify for the discount and free return. The 
  Smart-UPS 1000 was built for a rougher load than what I was using it 
  for, so I figured I could get by with a UPS that didn't offer as 
  much capacity. But how to tell just how much I needed?

  Once again, TidBITS search to the rescue! Adam wrote about buying a 
  UPS in 1999 (see "Don't Interrupt! A UPS Saves the Day, 1999-09-20), 
  in which he explained how to calculate the electrical load your 
  computer system will place on the UPS when the power fails:

<http://db.tidbits.com/article/5566>

    [L]ook on the back or bottom of each of your devices for power draw ratings in either amps or watts. If power draw is listed in amps, multiply it by your line voltage (120 volts for North America, 230 volts for Europe, etc.) to find the volt-amp (VA) load. If the power draw is instead listed in watts, multiply by 1.4 to find volt-amps. The problem with this manual calculation is that manufacturers tend to be conservative and publish the maximum power draw possible, which would in turn cause you to buy a larger UPS than necessary.

  Adding up the devices in my home office, I came up with a total of 
  1102 volt-amps. Not all of those were plugged into the Smart-UPS 
  1000 (which has a VA rating of 1000), but the number gave me a 
  reference for what to look for.

  Going back to the list of recommended new products, I decided to buy 
  two smaller-capacity UPSes. I chose the Back-UPS LS, which has a 
  model that is rated between 500-700 VA. With the trade-in discount, 
  I was able to buy each for $128 (instead of the $140 list price).

<http://www.apc.com/products/family/index.cfm?id=22>
<http://www.tidbits.com/resources/2009-02/back-ups_ls700.jpg>

  Although I ended up paying almost $300 (with tax and shipping), 
  instead of $150 to replace a battery, I now have two UPSes that 
  allow me to plug in equipment that previously was just in a power 
  strip and add more components if needed. And the Smart-UPS 1000 
  (along with an older, smaller UPS I retired ages ago) will soon be 
  headed back for responsible recycling, without my having to pay 
  shipping.

  So when you're evaluating your backup system, don't forget to take 
  power into consideration. A backup hard disk can't help you if it 
  gets zapped by a blown circuit breaker or a lightning storm.


Liquid Submersion Indicators Reveal Accidental Dips
---------------------------------------------------
  by Doug McLean <doug_mclean@tidbits.com>
  article link: <http://db.tidbits.com/article/10080>

  While it's no news that water and electronic devices don't mix, 
  Apple has of late rolled out an interesting and little-known design 
  feature: the liquid submersion indicator (LSI). Now integrated into 
  the design of all Apple laptops, iPods, and iPhones, the LSI reveals 
  whether or not its host device has been subjected to liquid damage. 

  As Apple clearly states on its support pages, "Liquid damage repair 
  is not covered by the Apple one year limited warranty or the 
  AppleCare Protection Plan." Thus, if your MacBook Air or iPhone 
  receives an accidental dunking, you're not going to be able to 
  convince Apple to repair it for free. Not as long as you have an 
  iPhone or an iPod manufactured after 2006, or any laptop produced 
  since 2008 - all these models include an LSI.

  For the iPod and iPhone, the liquid submersion indicator is usually 
  found in the headphone jack. Examining the inside of the jack with a 
  magnifying glass reveals a white dot at the end of the passage. This 
  dot turns half red or pink if the device has been submerged in 
  liquid. For the iPhone 3G the indicator is located on the bottom of 
  the connector housing, right under the 30-pin dock connector. 

<http://support.apple.com/kb/HT3302>

  While iPod and iPhone owners can view the LSI without disassembly, 
  the same is not true for the MacBook line. Apple doesn't say where 
  the LSIs in the laptops are exactly, but AppleInsider published a 
  diagram claiming to show their locations. The four LSIs in the 
  MacBook, MacBook Pro, and MacBook Air are spread out in various 
  points below the keyboard where they'd work well for detecting 
  spilled liquid. Again, normally white, the indicators turn red when 
  exposed to moisture, but even getting to them to determine if there 
  was liquid damage can reportedly take a technician up to 2 hours.

<http://support.apple.com/kb/HT3425>
<http://www.appleinsider.com/articles/08/10/15/inside_the_new_macbooks_lsi_battery_hd_and_ram.html>

  We can only assume that Apple's repair technicians had sufficient 
  evidence of people returning liquid-damaged devices under phony 
  pretenses to warrant the creation and implementation of these 
  indicators. It's also likely that the cost to incorporate the LSIs 
  in the new laptop models was small enough to make it worthwhile for 
  cutting down on repair fraud.

  On the user end, the most obvious concern is that these LSIs will 
  somehow indicate liquid damage when the device hasn't been dunked. 
  In particular, people living in extremely humid climates have voiced 
  concern that the indicators could misinterpret environmental 
  conditions and prevent them from receiving deserved support. How 
  much of a concern this should be is hard to say, given that the 
  information available on the nature or composition of these 
  indicators is slim. We did find a note from an Apple repair 
  technician passing on the claim from Apple that the indicators are 
  "very accurate" and "will not be affected by humidity or 
  environmental factors."

<http://uhbookstorecomputers.blogspot.com/2009/02/liquid-submersion-indicators.html>

  More troublesome might be actual exposure to liquid that activates 
  the LSI but does not, at that point in time, cause the device to 
  fail. Should the device need repair in the future for a seemingly 
  unrelated reason, that repair may be denied because of the LSI. 
  Water, for instance, doesn't itself necessarily damage electronics, 
  but can cause electrical short circuits that will. So if power is 
  removed instantly, and the device is allowed to dry, it may be fine. 
  Unfortunately, other liquids like coffee and soda may contain 
  corrosive substances or leave behind conductive residues even after 
  the liquid has evaporated. In such cases, the device may seem to 
  work properly for some time after the spill, but gradually become 
  flakier.

  The moral of the story? You already know to try to keep liquids away 
  from your devices, but if the worst does come to pass, you'll just 
  have to own up to the mistake and pay for repair or replacement 
  unless you have computer insurance coverage from a company like 
  Safeware.

Top 10 Screensavers for the 21st Century
----------------------------------------
  by Doug McLean <doug_mclean@tidbits.com>
  article link: <http://db.tidbits.com/article/9845>

  Now that screen burn is pretty much a thing of the past, we don't 
  really need screensavers anymore. And many people - quite reasonably 
  - prefer to have their computers go into energy-saver mode when 
  they're away for any significant amount of time. After all, what's 
  the point of displaying power-wasting patterns when you aren't 
  around to enjoy them? Fair enough, but there is still something to 
  be said for enjoying some interesting displays during those times 
  when you've just stepped back from the Mac for a short while. Today, 
  screensavers can do more than just display repetitive animations 
  (remember Flying Toasters from the After Dark screensaver?) and it's 
  worth investigating what's out there.

  When I went in search of new and interesting screensavers, I was 
  looking for three things: screensavers that could change and develop 
  over time, screensavers that made use of input devices or updating 
  information, and screensavers that put a fun twist on age-old tricks 
  like clocks or photo slideshows. Here's a look at ten of the most 
  interesting and enjoyable screensavers I found kicking around the 
  Web. Unless otherwise noted, all these screensavers are free.


  1) Electric Sheep

<http://www.tidbits.com/resources/2008-10/Electric-Sheep.png>

  Often cited as one of the best screensavers available, Electric 
  Sheep is both visually stunning and conceptually engaging. Named in 
  homage to the science fiction author Philip K. Dick's short story, 
  "Do Androids Dream of Electric Sheep?" this open-source screensaver 
  connects 60,000 sleeping computers to generate morphing abstract 
  animations. The process is mediated by a genetic algorithm - the 
  animations (or "sheep") with high user ratings go on to reproduce 
  with other popular sheep and produce offspring with shared 
  characteristics. Unpopular sheep eventually die off and enter an 
  archive. Users can also edit and upload their own sheep into the 
  gene pool. The end result is a spectacular collaboration and 
  competition between human design and computer algorithms. Scott 
  Draves, creator of the software, discusses Electric Sheep in an 
  online video (at 2:40 in). From a user perspective - and it's not 
  often my art degree proves useful in writing technical articles - 
  this screensaver really has the most impressive visual abstractions 
  of any I've seen. But what really makes it stand out is the user's 
  ability to collect new animations, and to affect the production of 
  future ones through voting (via the Up and Down arrow keys). The 
  endless number of new and different visualizations provides a major 
  reason to keep turning it on.

  2) Surveillance Saver

<http://www.tidbits.com/resources/2008-10/Surveillance.png>

  For the security guard in each of us, Surveillance Saver pulls live 
  feeds from over 1,000 different surveillance cameras all over the 
  world. The screensaver shows live images of city streets, parking 
  lots, Internet cafes, university libraries, highways, and more - 
  from all over the planet. Each live feed remains on your screen for 
  2 minutes before changing to a new one - unfortunately at this time 
  there's no option to adjust cycle times. My favorite detail of this 
  screensaver is the information bar located at the bottom of each 
  feed informing you of the feed's location, local time, and 
  geographical coordinates. Despite the camera's typically mundane 
  shots, the prospect of viewing an unfiltered slice of life from 
  places like the Czech Republic or Iceland is enticing. The current 
  alpha version is a little buggy at times - sometimes I would see 
  only a black screen, or the live feed would freeze up into a still 
  image. But this is a screensaver with enormous potential - and 
  hopefully it will continue to develop in future versions with the 
  addition of some controls. Nonetheless the current version is still 
  worth checking out; it will certainly satisfy your inner spy. Though 
  it's worth asking: What do I do if I actually witness a crime?

  3) BreveCreatures

<http://www.tidbits.com/resources/2008-10/brevecreatures.png>

  BreveCreatures is a screensaver that simulates the evolution of 
  virtual creatures. Beginning with randomly generated 
  block-creatures, the screensaver uses a genetic algorithm to help 
  the organisms develop locomotive capabilities. Each creature is 
  plopped down in a simulated 3D world and has a set amount of time to 
  move as far as possible from the start point - denoted by a yellow 
  star. Some creatures never budge an inch, and others speedily 
  scramble off - it's fun to watch one plop down and wonder, based on 
  its shape and parts, whether it will have any success. The 
  screensaver progresses through successive generations, each 
  generation utilizing the qualities of the most successful creatures 
  from the previous group. The result is a slow evolution towards 
  mobility. Because the process can take hours or even days for 
  significant developments to occur, each time BreveCreatures is 
  activated it picks up where it left off. This is all surprisingly 
  enthralling to watch. I found myself unable to turn it off - saying, 
  "just one more" - wanting to see if the new creature would be the 
  new record setter. It was also amazing to leave the room for an hour 
  and come back to see the progress that had been made. An interesting 
  addition for future versions of this program would be a video 
  highlight gallery that details the game-changing creatures that 
  significantly pushed forward the evolution of your system.

  4) Chemical Burn

<http://www.tidbits.com/resources/2008-10/Chemical-Burn.png>

  Chemical Burn is a screensaver that displays a transportation 
  network simulation. Packets of data are randomly generated with an 
  assigned destination (or node); these packets then attempt to find 
  the fastest way to get to their node. Frequently used routes become 
  faster; in turn, becoming even more popular and also more visible. 
  You can also select to have nodes collapse at random, and be sent 
  "Packets of Death," which destroy the receiving node and the 
  transportation routes connected to it. However, the destruction of 
  nodes and routes results in newly formed ones, continuing the 
  system's process. Another option is the capability to determine the 
  initial number of nodes (more nodes result in a more complex, but 
  slower, system), as well as traffic and distance weighting options. 
  While the animation is rather simplistic - you could be watching an 
  old Atari game - it's fascinating and relaxing to watch. Just 
  imagine the possibilities if this were redesigned with high-end 3D 
  graphics.

  5) Soundstream

<http://www.tidbits.com/resources/2008-10/soundstream.png>

  Soundstream is a screensaver that responds to sound input, whether 
  it be ambient room noise, your voice, or your iTunes music. 
  Flurry-like particles move about the darkened screen, shifting in 
  color as they go. Any sounds registered by your microphone cause the 
  particles to expand in size and brightness as they move. The degree 
  to which the particles enlarge, brighten, or shift in color is 
  related to the volume of the input. You can control the number of 
  particles, whether they exist in 2D or 3D space, and the sensitivity 
  of the sound responsiveness. If you like Apple's built-in Flurry 
  screensaver, you'll love Soundstream. After the initial fun of 
  yelling at my computer to watch the particles explode, I discovered 
  the subtler pleasure of seeing the sounds of my house visualized 
  onscreen.

<http://www.pcheese.net/software/soundstream/>


  6) iSight ScreenSavers

<http://www.tidbits.com/resources/2008-10/iSight-water.png>

  The iSight Screensavers collection ($4.99 shareware) is a group of 
  six screensavers that utilize input from your iSight camera, or any 
  other QuickTime-compatible camera, to morph through various effects 
  (not unlike the effects within iChat or Photo Booth). The six 
  effects include Fluid, Particles, Champagne, Fire, Water, and 
  Flipping Grid. I found the most impressive of these to be Fluid and 
  Water - though it's worth trying all of them out. Like Soundstream, 
  the iSight Screensavers are cool because they constantly respond to 
  the real time input rather than merely drawing from a finite set of 
  options.

  7) TimeLapse Screensaver

<http://www.tidbits.com/resources/2008-10/Timelapse1.png>
<http://www.tidbits.com/resources/2008-10/Timelapse2.png>

  TimeLapse is my favorite input-based screensaver. Like the iSight 
  Screensavers, it requires either an iSight camera or another 
  QuickTime-compatible camera. Once launched, TimeLapse begins taking 
  photos at designated intervals. Slowly, with the addition of each 
  new photo, it builds a time lapse animation. The screensaver shows 
  the animation in a loop, each time adding the recently acquired 
  photo or photos onto the end. Capture intervals, storage limits, and 
  playback speed are all adjustable. It's wonderful to see yourself 
  and your space captured in a time-lapse animation - and should you 
  leave your computer for a while, it's a fun way to catch up on what 
  happened while you were gone.

  8) Harry Potter Photo Show

<http://www.tidbits.com/resources/2008-10/HarryPotter-slideshow.png>

  Many people enjoy using Apple's photo screensaver as a way to 
  shuffle through their digital photo collections. The Harry Potter 
  Photo Show screensaver offers a fun twist on that basic concept. 
  When launched, Harry wanders around a Hogwarts library casting your 
  photos as spells with his wand (above you can see Harry casting the 
  TidBITS masthead). The photos hang in the air flittering and 
  flickering as you would expect a good spell would do. You can adjust 
  the music, lighting quality, source folder, and how the sparks that 
  shoot out of Harry's wand act when casting. Despite the mediocre 
  animation - Harry looks a bit like a claymation Muppet and moves 
  around woodenly - it's surprisingly enjoyable to see him zap your 
  pictures with his wand.

  9) Pong Saver

<http://www.tidbits.com/resources/2008-10/Pong-Saver.png>

  If you often find yourself yearning for the video game aesthetics of 
  yore, you might enjoy this simple but amusing adaptation of a clock 
  screensaver. In Pong Saver, the score between the two sides reflects 
  the time in either a 24 hour or 12 hour notation. A hint for you 
  gamblers out there: Don't place any bets on the hour hand side - it 
  almost always loses to the minute hand side.

<http://rogueamoeba.com/freebies/>


  10) LotsaEscher

<http://www.tidbits.com/resources/2008-10/LotsaEscher.png>

  Many people are familiar with the mind-bending illustrations of M.C. 
  Escher. The LotsaEscher screensaver takes a dizzying journey into 
  the heart of Escher's 1956 lithograph "Print Gallery." The 
  screensaver is based on the work of Hendrik Lenstra and Bart de 
  Smit, who, through an analysis of the mathematical structure of the 
  image, were able to uncover the mystery of the blurry white hole in 
  the center of the drawing, and were able to create a Droste image - 
  an image that contains itself in miniature. The screensaver zooms 
  infinitely into various versions of picture - you can select which 
  one in the Options panel. It's a vertigo-inducing way to spend some 
  time.

<http://en.wikipedia.org/wiki/Droste_effect>


  11) Flurry Spoof

<http://www.tidbits.com/resources/2008-10/Flurry-spoof.png>

  There's no point in downloading this gag screensaver, which is an 
  advertisement for the German jobsintown.de employment service; just 
  watch the preview on the site. It's a great spoof of Apple's popular 
  Flurry screensaver.

<http://www.avocada.de/2008/en/jobsintown/screensaver/>


**More Screensavers** -- As you might imagine this list only begins to 
  scratch the surface of the screensaver universe. If you're looking 
  for more, I recommend checking out Pure Mac Screensavers and 
  XScreenSaver as good starting points. Pure Mac Screensavers has a 
  wide variety of interesting programs - some of which made this list. 
  It's easy to navigate and many of the screensavers on the site are 
  worth trying out. There's also MacScreensavers, though this site 
  seems oriented toward promotional and pop-culture screensavers, most 
  of which are unimpressive examples of the screensaver genre.

<http://www.pure-mac.com/screensaver.html>
<http://www.jwz.org/xscreensaver/>
<http://www.macscreensavers.com/>

  XScreenSaver was the standard screensaver collection on most Linux 
  and Unix machines running the X11 Window System. The first version 
  was released in 1992, and was ported to Mac OS X in 2006. Here 
  you'll find a wide array of older screensavers with some old school 
  graphics and some endearingly simple premises. (Thanks to reader Dan 
  O'Donnell for the tip on XScreenSaver.) 

  Oh, and if in your explorations you come across any screensavers 
  that seem interesting and weren't touched on here, I'd love to hear 
  about them. Happy screensaver searching! Enjoy!

ExtraBITS for 23-Feb-09

  article link: <http://db.tidbits.com/article/10089>

**XRoad's Map Apps Boast Turn-by-Turn GPS Directions** -- Despite the 
  belief that Apple wouldn't allow turn-by-turn directions in an 
  iPhone app, the recently released version 1.2 of XRoad's G-Map U.S. 
  West and G-Map U.S. East adds that feature. Unfortunately, still 
  absent are voice prompts, which XRoad attributes to Apple's 
  prohibitive policies. The two apps, covering the eastern and western 
  halves of the United States, are $19.99 each. (Posted 2009-02-19)

**Go Beyond Google Searches** -- Believe it or not, there are other 
  (and sometimes more effective) ways to find information on the Web 
  than using the Google search box built into your browser. Joe 
  Kissell explores some of the interesting alternatives in this 
  Macworld article. (Posted 2009-02-17)

<http://www.macworld.com/article/138781/2009/02/beyondgoogle.html>


**Mobile Web Usability Stinks** -- Let's be real. Browsing the Web on 
  a mobile phone, even an iPhone, is a lousy experience in comparison 
  with using a full-fledged browser on a Mac. Jakob Nielsen explains 
  the problems and offers suggestions on how to improve mobile Web 
  usability in his Alertbox column. (Posted 2009-02-17)

**The Tao of Backup** -- The software this 12-year-old site was 
  developed to promote may be long gone, but its lessons about backup 
  are timeless. "Remember, Grasshopper, to believe in one's backups is 
  one thing. To have to use them is another." (Posted 2009-02-17)
