Earlier in the year I made a Kinect hack in the form of an interactive music visualiser. Amazingly Microsoft have picked up on it from my YouTube video. They've been featuring it at the E3 games conference, where it's going into a public vote against 5 other hacks deemed by them to be the best out there. The app with the most votes will be released as an app on the Xbox.
This was my effort...
Loads of fun.... and it gave me an excuse to play Electric President's 10000 lines (very apt).
Be sure to vote and check out the other hacks...
Thanks very much!
