caustic texture

[MrH2o]

Hello

I'm looking for a good photoshop tutorial on how to create a realistic caustic effect (as seen below)

I'm thinking of using it for some web page maybe so if someone have a tutorial on how to animate it would be gold (alto its not necessary)

I've seen the effect in some games so I thought some of you must know.

it's a generator ... even for animations

nice toy btw
