It's a neat concept- structures built out of food cans and food items (non perishable) by architect firms. They can only use minimal other items. When the competition is over, the cans all go to the local food bank.
Here were my favorites from the Pensacola competition:
Seville Quarter Fire Truck
Sushi Rolls (seriously, how cute is this!)
Cheeseburger in Paradise (with fries and a drink!)
