Aqua V

From Gtony:

Aqua V is a Fish Tank Screen Saver developed in Direct3D. This Screen Saver is fully customizable. You can create you very own personal fish tank, you can select which fish youd like in the tank from many different real-life fish, they are completely rendered in 3 dimensions and look true to life. Then select your tank; they too are in 3-d. This allows you to pan and zoom in on your fish to enjoy in detail. Their movement is so life-like and realistic youd swear AQUA V has just filled your monitor with water and dumped some fish in there. You can even select the lighting and create an ambient environment for your fish. The type of gravel is even selectable. If you like you can personalize your tank even more by adding any picture of your choice to the background of the fish tank. Try Aqua V now and relax to the fluid motions of aquatic life.
