Thanks to everyone who replied about my radiosity question. I have
one last request. Can someone tell me where to ftp some radiosity
rendered pictures (hopefully gif, even better would be IFF) so
I can see how much better a radiosity scene wuld look in comparision
to raytraced diffuse-light scenes.
Also, wouldn't it be possible to combine ray-tracing and
radiosity? Something like applying the radiosity technique after
specularity has been applied?

Something like applying the radiosity technique after >specularity has been applied? Yes, this has been done and there are many papers describing various versions of this technique.

Greenburg Siggraph '87 p.311-320 "A Ray Tracing Solution fo Diffuse Interreflection" by Greg J. Ward, Francis M. Rubinstein, and Robert D. Clear.
