To test the possibilities of Ligthwave 7.5

Looks good. It really needs to get some prismatic abberation into the light though to set it off.

There's a rather good tutorial that esplains the technique here:

Wouldn't setting a prismatic effect on the clear portion of a cd work aswell?

I don't know what you mean with prismatic effect, but I guess is more rendering time and I did not want to wait too much

Well, I was inspired by an image I saw in the V-Ray page and I wanted to achieve the same effect if possible
