works great here. very well done.
the only 3 things I'd criticise:
-it's too easy to create weird effects, when sliding the sliders around a lot. but with a bit of playing and experimenting, it's fine.
-i'd like to enter values instead of the sliders. sometimes it's hard to get a value between 1 and 10 when the slider goes from 1 to 500.
-the tiling is a little obvious when you try to get very small waves... but I guess higher res-textures should get rid of that effect.


nice work!
