head tracking 3d camera

Using OpenCV's Haar cascade face detection functionality, I was able to throw together a real time head tracking program. I coupled this with a 3D "virtual window" demo, a homage to Johnny Lee's Wii-based head tracking demo. Performance is surprisingly good. On my 2.16 Ghz MacBook I am tracking at 16 frames per second - sufficient for real time interaction with no obtrusive reaction delays. Additionally, I've optimized the code so that only 50% of a single processor core is consumed (and that's on my relatively slow laptop).
