PCG has the news on Carmack's latest side-project, which is making a VR kit. Carmack showed it off behind closed doors at E3, allowing people to play Doom 3, with full-on surround-o-vision. Carmack says: "This is literally held together with duct tape, but the guts of this is going to be made available as a kit for around $500.” (Update: Apparently this guy is also responsible for a lot of what they're up to.)
So not a commercial thing, but a do-it-yourself VR system with Carmack's brain behind the gadgetry. I'm getting one. For research and development purposes, you understand. Anyone else?
