Hi,
What are you showing?
Can you give us a explanation about the symbols?
Thanks,

Thanks! I started with a font object, but it didn't look right. So, I used
POVRay to make a b/w image for each glyph, then blurred it a bit and made a
height field with each one.

Well, it is a _bit_ more complex than that, but all the layers I made didn't
seem to help much. See below for the code, and maybe you can give me some
suggestions?

Ok, I tried to fix that.

I added area lights and a secondary light. I think it helped a lot!
Here's the texture code. It's supposed to be some kind of stone. Any
suggestions?
