For those who have everything: The Local River aquarium

The Local River aquarium functions as both “an alternative to the standard (boring) fish tank” and “a fully functional refrigerator.” Freshwater fish can be raised in the tank, and their water will be cleaned by the plants above, which grow by feeding off the fish’s waste. Devoted locavores thus eventually need travel only a few steps from their kitchen to harvest enough fish and greens for dinner. And even if you don’t use the Local River tank as a source for food, it’s “pretty cool looking.”
