John Carmack is making a virtual reality headset

John Carmack has been building a virtual reality headset in his spare time. He's showing it to people behind closed doors at this year's E3, tucked away inside the Bethesda booth, and described it as "probably the best VR demo the world has ever seen." Our video hero, David Boddington, was the 30th person in the world to use it.Check the link for a 20 minute video with Carmack on virtual reality, why he decided to tackle headsets, the latency of the human mind, and the first footage of one his handmade prototypes.
