Ever since I saw the Kinect work I new it would change user interfaces for ever. No more sharing germs, just hand gestures like on minority report. As I told my tech friends (comp techs not devopers/programmers) about how it would change every thing they all blew me off. Then I start trying to think how much time would I have to make something that works with kinect and when stuff will start being released. So heres the first project someone did. Has unlimited potential.
