Interesting. I'm stereoblind as well. I wonder if it would work for me as well. I've had moments during 3d movies where I think i'm seeing 3d, but not sure if it's only due to much larger screen that imax movies are generally shown on. It usually happens on sparks or rain or things that are really flying towards you and i'm wondering if that's similar to what you describe as 'instances where the parallax is very large'.

I may have to get an Oculus rift and try the same demo. It would be really amazing to be able to develop some learning tools for people to retrain the part of the brain responsible for stereovision.
