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
Option-Click AirPort Menu for Network Details
If you hold down the Option key while clicking the AirPort menu in Mac OS X 10.5 Leopard, you'll see not just the names of nearby Wi-Fi networks, but additional details about the selected network. Details include the MAC address of the network, the channel used by the base station, the signal strength (a negative number; the closer to zero it is, the stronger the signal), and the transmit rate in megabits per second showing actual network throughput. If you hover the cursor over the name of a network to which you're not connected, a little yellow pop-up shows the signal strength and type of encryption.
