Ever wish you could jump into Second Life? Researchers at the California Institute for Telecommunications and Information Technology (Calit2) almost can with the StarCave, a third generation virtual reality space. The pentagon-shaped room consists of computers, rear-projection walls, and floor screens, and displays over 68 million pixels. The room supports 20/40 vision when the users wear lightweight, polarized sunglasses. At a cost of about a million dollars, the StarCave works by pointing a wand to go through the 3D images and/or zoom.
