It’s here, in beta form!

As part of Microsoft’s SDK launch event, then held a 24-hour ‘code camp’ in which small teams had 24 hours to produce something cool with the Kinect. I was invited to participate, and made a simple app that turns the user into a cylon! It turned out quite well.
You can see the video currently up at http://channel9.msdn.com/live. Scroll to roughly 2:20:00 to see me bumble around on camera.
I also got a chance to wedge in a really basic Kinect-powered PowerPoint presentation viewer. It existed in OpenNI first… so not really in the spirit of the code camp, but what I thought was remarkable was that the Microsoft SDK is easy enough to get into that I was able to port it while sitting on the couch waiting to go on the air at the channel9 building. Well done Microsoft!
