I guess so...

Because it works by placing multiple concentric rings of ripples 
semi-randomly. Now if I place the centers of those ripples to coincide 
with the edges of the block, the ripples will follow its outline. (This, 
apparently, is how the Real World(tm) works...)

Mmm, OK. In that case, my water is going to be completely black...

Is IOR=1.3 "realistic"?

Here's a random question: does LCD require gamma correction?

OMG... you created something 17,826% better than what I had in about 20 
seconds!
