LotsaWater Screensaver

Another cool screensaver for Mac OS X:

LotsaWater: "This screensaver renders a fairly realistic water effect over your desktop, showing it distorted through the wavy surface of the water as raindrops fall on the surface.

It uses quite a bit of CPU power. There are configuration options to vary the accuracy of the simulation to fit the processing power available."

Thanks to Doug de Stwolinska for finding this one!
