I was thinking for gaming especially with the 3d glasses it might be neat to have a larger curved screen to fill more vision area, probably also with the 3d glasses. If it is a wide enough field head turning would be possible, although theres some hardware limitations unless the screens can be made small and light like glasses or a helmet with head movement tracking. Also a round treadmill for jogging in the game is cool too.

Also on the 3d screen topic, it might be practical to track movements with something like kinect. This could control a circle treadmill-like machine in real time to cancel out movements. The screen could be lasers. The lasers would have a high resolution and "low" power, and track power and tracking via the kinect system to aim at the user(s)' eyes.

Instead of (or sort of with) lasers one could use fiber-optic conduits of a known length to direct the light and control the power. This would require a cord between the video card and something that may or may not resemble glasses, maybe with a neat hat. Light will follow a reasonably pure clear material sandwiched between opaque or reflective materials pretty good hopefully, so you can just point a screen at one end of a glass fiber with a lens in front of it, and put a lens on the other end and the light pattern is conserved.

You mean something like this or wider? http://www.gohacking...itors-next.html
