I looked at the animation. From your post I gather
you're using bicubic-patches?

The other thing: I think that the frequency of the waves
can impossibly be higher than the frequency of the mesh.
They're dependant on each other, the smaller the mesh,
the faster waves will move, the "grainier" they look.

The implementation suggested that waves aren't fully circular,
so I guess that's not you're fault...

But Rune should speak up, he knows a little more about those
matters!

Good start though.
