Virtual Fish Tanks
Above is a virtual fishtank restaurant in Japan.
Also check out this Virtual Fishtank that Nearlife did for the Museum of Science in Boston a few years ago.
What makes VirtualFishtank.com different from any other website is the ability to Build-Your-Own-Fish online and release them into the Virtual FishTank(TM) exhibits at the Museum Of Science, Boston, and the St. Louis Science Center.
