A Japanese firm has used Microsoft's Kinect peripheral to create a promotional display for the upcoming Ghost in the Shell: S.A.C. Solid State Society. The exhibit features images projected on two different walls, and then uses the Kinect to track player movements, allowing visitors to control one of the mechs featured in the movie.
The system itself is actually PC-based, however, so it's not official Xbox software. If you happen to be in Tokyo and want to see it, the promotional exhibit is on display in the Shibuya Parco shopping complex until the middle of April.
