While the program is great, I thought I might point out a few bugs:
The starfish has some issues when climbing up the "glass". It is best described by a picture.
There is no method to cycle the random fish. Pressing the spacebar twice does not work.
If you put it in fullscreen mode from the application, white lines flash at the top of the display. Quite annoying. It does not happen in the screen saver.
There is one other major bug, please contact me at

If it helps at all, the program is running on a stock 800mhz PowerBook G4.
