>MS could find the middle ground between lush 3D VR-like environments and the real world. Back around 2000 a Slashdot article reported an attempt to create a human-sized hamster ball constructed of a semi-opaque projection-friendly surface. The ball would sit on some sort of roller mount. Five projection screens surrounding the ball would project a virtual environment over the "port", "starboard", "fore", "aft", and "north" surfaces. A human occupant would enter the ball, and, based on his movement detected through the roller base, be presented with a continually updating holodeck-like virtual environment. Perhaps something like this is still in development somewhere.
