It may not be quite as exciting as the famous toilet fishtank, the Aquariass, but these retro-television sets adapted into working aquariums are functional art. Paul Leibow turned this set from the 1940's into the fully operable Inca Telegenic Aquarium. All of these pieces are one-of-a-kind and the prices reflect that. The Inca is $7500, the lowest priced model, the Silverstone is $3400. Custom designs are also available at inmod.
