I did this for a school report on how raytracing works.  (I got to pick to
topic.)  CSG and a couple sphere_sweep's, textures all from standard
includes.  Comments?

Thanks.

Just one: don't!
I once tried to explain the class what raytracing was and how it works.  They
thought it was boring and far too technical.  I couldn't have picked a worse
subject to talk about :(

The red one is glass, although it isn't real obvious.  Hmm...

he is right!  Replace the torus from the "a" with a chrome sphere! :)

Not a bad idea, actually...  I'd have to retexture the "g", since that's
chrome right now.  Hmm...  Now I know what I'm doing this weekend!  :-)
