So I see :) I guess you are rotating R,G,B independently with some random numbers? It gives quite a nice effect, I agree.

My reason was not unsimilar, although I started out with the program TextTone. Some guys in a HTML-enabled forum started the "color wars", with <font> tags, and I thought I'd show them what nukes look like. Silly, sure, but it seemed like a great idea at the moment. Lots of things do. *Grin*
