Larry Smarr on-camera: text

"The CAVE" has several roots. One is just an acronym. But I think the more interesting one is from Plato when he was talking about the world of ideas and their representation in the physical world. And he had a parable of how men were standing in front of a fire, but their shadows were projected on the wall. And if you could just see the shadows you could infer that there must have been something physical there, but you were looking at something that was essentially imaginary. And the CAVE can give the il lusion of being in physical space: you walk in, you see you body and so forth, and yet, in a way, it's a shadow of a digital world.
