It's obvious that the Kinect is not designed for this, and it's going to be pretty basic level stuff for the price point. That said, it's incredible what people are doing with the hardware without a programmer's manual. I'm finding all this fascinating - I hope he's able to clean up the sampling and make the 3D model more robust.
This, people, is proper 3D Film in the making. Imagine a TV where the scene is rotated using a Kinect to determine your position, and the film is a 3D model being played back made, interestingly, using the same kit as used for playback.
