Also used sqrt(2), but hard-coded .707, that's sufficient
and faster than having the CPU calculate sqrt(2) all the
time.

How do you read the pgm-file? I've got no experience
with reading other files than those I've scripted myself.
But using an image as a base, wouldn't that be a
bit complicated if you'd want to set you're water surface
different than on a horizontal plane? Also, if you have
surrounding objects to block the waves, it would be
difficult to match splashes with surrounding environment...

BTW, how interactive is your system?
