This scene only has one camera, it's more like a one-way wormhole. I'm 
trying to get it to use cameras, though...in that case, the result will 
be the same as rendering with another camera and using that as an image 
map, except with essentially infinite resolution, much less memory, and 
much easier to use animations.

Well, it *is* a pigment...if you don't use ambient 1, you see that it is 
really colors on the surface of an object that will get shaded like 
anything else.

Well, light going into the "far" end of the portal should pour out of 
the "near" one, but that won't happen. Well, it should be possible with 
photon mapping, but I don't know how it would be done...it would 
probably require it to be a new object type instead, and wouldn't be as 
flexible.
