I don't have time to read through the thread today, but I did before the Rift kickstarter was announced, and my impression has always been that the software-distortion-in-compensation-for-simpler-optics[1] idea was already out there when Carmack chimed in. 1. Allowing the screen to be much closer, drastically improving practically achievable FOV. Here's the thread: http://www.mtbs3d.com/phpBB/viewtopic.php?f=140&t=14777 http://www.mtbs3d.com/phpBB/viewtopic.php?f=140&t=14777

Of course it was - the barrel distortion system was originally developed in the 1990s for and by (?) LEEP: http://www.leepvr.com/ http://www.leepvr.com/ Back then, the optics were key - and very expensive - but while the optics were originally used to warp then unwarp the image (ie - analog warping), it was thought that the warp portion could be done in software (but computers at the time weren't powerful enough to do it real-time). I believe that Palmer was fully aware of this, and when the LEEP optics patent expired, realized that a cheaper version could be made, and combined with other parts coming on the market (particularly lightweight, large, high-res phone displays) to build a "dream" HMD.
