"Local River" at home?

Want to have a nice ecosystem in your living room? Mathieu Lehanneur designed something called a local river. The local river consists of blown glass, a water pump, plants and fish. The concept of the local river is to help the "lacavores" in San Fransisco. The concept is to have your own vegetable garden in your home. The plants on top of the enclosed glass case will extract nutrients from the fish. And in turn the plants will act as a natural filter for the fish and purify the water. This maintains a healthy balance for the fish to live in. This process is similar to fish farming and the same technique is used just on a larger scale. Ideal fish used in the Local River are typical fish-farm fish such as eel, tilapia, trout, perch, carp etc.

The lacavores define themselves as "a group of culinary adventurers who ear foods produced in a radius of 100 miles around their city.

This is a really cool idea. It would look great in your home and you can snake on home made vegetables as well.
