Pencil Sharpening: Virtual Fish Tank

You get to create your own fish (using Shockwave) and to release it into the virtual aquariums of the St. Louis Science Center and the Museum of Science in Boston. Once you've unloosed your fish, stats are generated about its impact on the aquarium's ecosystem. If you happen to visit either museum after creating a fish on line, you can retrieve your fish and release it into the museum exhibit on site. Registration is required to participate, but no personal information is extorted. <http://www.virtualfishtank.com/>
