Vertical (Diagonal?) Farm from Work AC in NYC

We love vertical farms and while they may not be as practical as green roofs, the idea of food being grown right in the city doesn't get any more local than this.

Underneath is what appears to be a farmers market, selling what grows above.

"We are interested in urban farming and the notion of trying to make our cities more sustainable by cutting the miles (food travels)." - Dan Wood, design-company official
