If you visited Boston's Museum of Science, you'd find they have a virtual 24,000-gallon fish tank on display. Instead of real fish, this one is populated with lively animated creatures created by museum visitors. Children can select how the fish looks, how it eats, and how it behaves when around other fish. Then they "release" their custom design into the "tank" and watch it interact with other aquarium residents. With VirtualFishTank, you can experience all the fun without leaving home. Your fish will swim in a special online tank at first, but then you can release it into the big tank at the museum, and watch its antics there.
