this idea is stupid.
the kinect, requires such a large living room to work than anyone with less cant use it as it stands.
than this comes around, and the only way it can function is if you dot have anything on the walls...
but lets also not forget, even a crappy 720p projector is over 500$, and than, scaleing a 720p image up to a wall size would look like hell
and 1080p puts you into the 900$ range for one that isnt even great.
needing at least 3, 1 per wall, and they would look like hell, i just cant see this as doable...
WHY cant they just use head mount display like sony/valve/carmack are? that is FAR more promising than this crap.
