Aquarium/terrarium combo.

Cool, but not exactly a "terrarium"...aquaponics combines hydroponics (feeding plants via water) and rearing fish. Usually it's more economically beneficial when you are raising the fish for food too. The water is likely pumped through the media bed of the plants, collected, and fed back into the aquarium.

I've never seen one built into one cabinet though. Neat way to do it and make it better looking to the eye.
