Some time ago a couple of guys were able to hack the Kinect so it is possible to use the camera on a regular PC or even a Mac. It was only a matter of time before people would start to show off on YouTube what can be done with the Kinect was some added self-written code. Here are (only) two examples of those videos. The beginning of a whole new scene of Kinect wizardry?
You can watch the videos after the jump.
