That's the link.

I downloaded BMRT, but so far I can't do a thing with it. The interface (if you could call it that) is right out of the Stone Age. If anyone knows of a good tutorial for Idiots that might get me started I would be grateful.

I also stumbled across a thing called PovRay, which also looks very interesting. Considering the quality of the renders I'm surprised there isn't more interest here at Renderosity.
