Interesting project, but projectors always have the issues that they project shadows as well and unless you have every area filled in a redundant way, you will end up breaking the illusion when you enter the room and project your own shadow. On top of that, I am not sure if there's much to do, game-wise, in such an environment.<p>EDIT: I'd be more excited with Full Room VR experience, using Kinect devices everywhere to detect your movements, hands and so on.
