Los Angeles-based artist Ramon Coronado made furniture from shopping carts. He calls the project "Mercado Negro" and his ambition lies in "reclaiming an ordinary, everyday object and transforming it into a whole new object." At the link, you can see many more pictures, as well as photographs from his workshop as Coronado constructed these pieces.

"I took it upon myself to take a shopping cart and make a statement with it."
Ugly in, ugly out. But interesting at least.
