Thanks Bill, that is a very amazing shape. So amazing, in fact, that I just had
to try it out myself. Being perhaps a little too eager I made it glass, and
added photons, radiosity and a "grid"... ;)

....Unfortunately, I find out too late, I think it slightly intersects the ground
plane. But it took about 2 and a half days to render in 2 threads on a
dual-core 2.4ghz PC so I won't be reattempting this until just before I go away
over Christmas. I would love to try it with an HDR background but I am not sure
how to get photons set up to shoot from a background image.

Anyway I thank you again -- I now have, at the very least, an interesting
wallpaper for my desktop!

P.S. I have scaled back the quality settings a bit 'cause at high quality it was
still 462kb even as a JPEG (is that too big for this group?). If anyone would
like it though I will post the full version upon request (original render is
+w1280 +h1024 +a0.0 +am2).
