Here's some cool caustic stuffs.

Cool is right! The orbs have a very surreal look.

cool experiments. i like the disco ball / light optic thing. ---> how did you do that one?

are there tutorials on caustics?

Awesome stuff!!!

Thanks, the orbs are pretty neat. I added a bunch of surface craters to give it a banged up frosted look. And yes, there are tutorials on caustics. Let us turn now to the wonderful world of Yves.
