Thanks, I've bookmarked your links.  I'm in the process of experimenting
with image and maps for colors, logos and bumps now.

I've mistakenly called two things something else I've just realized. So if
you see this Thomas please excuse my bumbling. To correct myself: I used
'sor' not 'lathe' for the bowling pin, and I called a bicubic_patch a
bezier_patch in my email to you. I almost always make that mistake. Sorry
to be messing up wording when talking to a new POV-Ray user, hopefully
you'll see my mistakes anyway yourself.

I am not really a new Pov-Ray user I have been using pov-ray for about 3
years. Oh did you mean Tim Hutcheson?
