An anonymous reader writes "John Carmack, co-founder of id Software, is using his spare time to develop a modern virtual reality headset. After purchasing such a device last year, Carmack became frustrated with how slowly the technology has progressed over the past twenty years. So, he decided to push it forward himself. PCGamer reports that he's been showing off his prototype behind closed doors at E3 this year, and has an interview with him about the problems with VR and the technical challenges he needs to overcome."
