Anyone remember those huge VR Goggles they used to make? Suppose you combine the Icuiti VR Glasses with Nvidia's Quadro FX 4500 Graphics card. Now all you'd need are supported applications. QuickTime VR is fun to play around in with Bryce but a true VR world, ala Second Life, with support for stereo displays, head tracking, and the like would be fun to play with. Anyone playing with this sort of tech?
