Here is a little diversion you might enjoy. The Rock Fish - they look a lot like gold fish, but gold comes from rocks, so give me a little poetic license - anyway, these fish can sense your mouse just like real fish will sense your finger inserted into the pool. You can feed the fish by clicking the mouse. If you click in a bunch of different places you can get the school to split. I've never been able to get it down to individual fish - but I'm not done. Enjoy.
