Seems like a really neat idea. I love the idea of being immersed in a video game without having to wear headgear, or building a $50k crazy setup. Obviously the point of this type of setup is different than a fully 3D interactive experience. I'm guessing the effect is pretty powerful, because really, all you need to focus on is the center of the action (the tv), and the peripheral information could be low-res, and blurry and still help with the immersion.
