I on a computer system company (Computer Systems Services)
and a little birdy tells me that there is something on the horizon from a company (cannot say) that is creating a fully functional motion sensing enclosed head gear (enclosed as in it looks like a dive mask so no "outside" light can come in) he first model will support 1024x1786x32 and 1280x1024x32,
a small sensor mounts on top of your monitor and tracks 3 nodes on the helmet, which thus alters the picture, I MAY be slated to test to make suggestions and to test it with systems. ohh and one more thing the price on it will be WWWAAAYY cheaper than you think.
