Thanks :-)

The higher the specular value, the more defined the highlight becomes.

It added a highlight to the table. The trick is that it makes the surface
look less uniform.

No problem! :-)

Sure, you can fire off POV-ray with pretty much any language -- it's just a

I'm glad I was able to help and I really liked that scene! It would be the
perfect scene for a tutorial too.
