oh my, i just read through and seen that Q2 stereogram, very cool, but it would be kinda hard to get used to...its quite cool with the animated gif ones, it never actually occurred to me that those things could be animated, let alone be made as a mod or such for a game...i kinda want to give that stereo Q2 a try

...animated gif ones? where?
I patched ezquake (quake2 engine) with Lewey's code and it works, it's pretty cool to see..

Unfortunately it's pretty much unplayable - you cannot distinguish doors, or small items.. Normally when you see an autostereogram, you see it in "space" - so maybe space maps would be better, but I did not try. I can send you the patch if you want to compile it and see how it works, I had to make some changes to make it work.
