I have an archive of several gig of information, papers, code, software, images - you name it - that stretches back detailing VR to at lease the Ivan Sutherland "Sword of Damocles" era (and actually, before that even - plenty of stuff came before his demos that hinted at things - Hugo Gernsback had more than a few covers of his pulp-scifi mags that covered VR and AR ideas in the 1920s and 30s, for instance).
Do most people think that VR is a totally new thing?
