It has been a while since a hacking project has gotten people excited - with more and more companies clamping down on their hardware, the hacking "scene" has not been twiddling their thumbs.
Enter, hacked Microsoft Kinect.
Someone has taken the open source driver and plugged the Kinect into his own multitouch UI "TISCH" software library (which already supports the Wiimote as an input). The result of this is an Microsoft Surface-esque multitouch interface which has picture shuffling and zooming - but this amps it up a bit by using the full body tracking instead of the touchscreen input.
Are you an Apple user? Well, you're not left in the dark... it also works on OS X!
