I had posted this yesterday, but it never showed up. Let's start again.

I have promised to BillyGoat to show his image here for the following reason: He wanted to participate to our challenge, but as he was working as a volunteer at
Renderositys booth at Siggraph, he missed the time limit and has posted it when we already started to vote.

It's a pitty, because this one too was a very beautiful WAVE image:-)
