SereneScreen Marine Aquarium

This screensaver turns your OS X desktop into a virtual aquarium. You can choose from several kinds of tropical fish that swim around the desktop of your Mac. These fish are actual 3D models, not flat images dragged accross the screen. Lighting effects simulate the sun as it passes through the tank, a realistic-looking starfish very slowly moves around the tank, and an air pump produces realistic-looking bubbles if your graphics card can support it.

Requirements:

Mac OS X

Limitations:

Only 3 different fish types at one time
