@Bas: That's great. Are you going to release it to the public any time soon?
Now that I have a Kinect (thanks to Laura Foy and Paul M.) I've been looking around for interesting demos to try out.
So far all the MIDI controller apps use OpenNI and some of the earlier "hacks" so I haven't been able to do a whole lot with it. Of course I've only had it for 3 days
