Since the Kinect was launched there has been quite a few people who are a lot smarter than us working on opening up the Kinect device for use on PCs.
This didn’t take very long to do and once it was fully hacked a stream of homebrew content for the Kinect came out. This one in particular has to be my favourite. The guy goes by the name of Roboczar and has made a synthesisizer out of the Kinect device by using different shapes on a piece of paper. I could tell you exactly what it does but its better to just watch the video here .
