Here are three different versions of the same render. Some marbles scattered on a table.

I had a hard time picking which one is my favorite so I thought I could just put all three into one final picture. The first image on the left is a lightwave render (no caustics). The middle and right are the same render, but with added work in Photoshop elements and a little work with Paint Shop pro. Each one has a different color and lighting to it. Comments welcome.
