Well, I had not planned to enter this, but Dries just posted a .ksp of his now famous "Aquarium Box", and I just couldn't resist! A client gave me this skull years ago for a medical product, and he/she has come in quite handy!

WHOA ! I didn't know Keyshot could do caustics!
Just had an idea, I dint know if you wanna follow up on it, but it would be cool if you ambient the box like a shot inside a pond where the skull is sinking down slowly, and with those caustics you could really get some nice imagery. ;)
Either way you got a really cool concept here!
