This video demonstrates the potential use of head tracking in computer games. The TV used is a standard HDTV hooked up to a computer and a Wiimote. Skip to 2 min 30 seconds in the video to see the amazing results that can be achieved using simple head tracking technology. This really would be amazing for playing games. Apparently this very gentleman has been hired by M$ to work on Natal, so fingers crossed.
