Eric's right, the cave system was/is used primarily for high end
visualization; i was just suggesting that if you want to project on
all surfaces, you wouldn't have to use steroscopic vr, but its a good
place to look for the technology to integrate multiple surface
display...in 5 minutes of googling i haven't found the inital
reference i remember, but have found several papers on low cost
solutions using open source software.....nor do they have to be
millions of dollars.
