I updated my VR post just above. Has link to original developer/author's article.

Makes me think I still want only a real good headset that I can wear sitting in a chair -- not a full VR setup.

I would only use it as an inutitive "wrap around" replacement for "Eyfinity" multi-screen and TrackIR5. I would NOT use it standing up in an empty room.

Good news is that simple "sit in the chair" 3D glasses (semi-VR) are going to be much much cheaper, apparently. And, I could use them with most games.
