By recording and processing the direction of light rays entering its sensor, the forthcoming Lytro camera promises to provide previously impossible features, such as the capability to focus on any part of a photo, at any time, or even bring an entire photo into focus at once. The camera isn’t slated for release until later in 2011, but you can play with refocusing photos and read more about the technology on Lytro’s site now (the picture gallery requires Flash on a Mac, but does work in iOS via HTML5). follow link
Opening a Folder from the Dock
Sick of the dock on Mac OS X Leopard not being able to open folders with a simple click, like sanity demands and like it used to be in Tiger? You can, of course click it, and then click again on Open in Finder, but that's twice as many clicks as it used to be. (And while you're at it, Control-click the folder, and choose both Display as Folder and View Content as List from the contextual menu. Once you have the content displaying as a list, there's an Open command right there, but that requires Control-clicking and choosing a menu item.) The closest you can get to opening a docked folder with a single click is Command-click, which opens its enclosing folder. However, if you instead put a file from the docked folder in the Dock, and Command-click that file, you'll see the folder you want. Of course, if you forget to press Command when clicking, you'll open the file, which may be even more annoying.

Otherwise, you'll be left scratching your head for a while - like I was - wondering what the fuss is all about. :-)
