Canstruction is an international charity competition that opened last Thursday at the Winter Garden and Courtyard Gallery of the World Financial Center, featuring giant structures built entirely out of cans of food. Top architectural and engineering firms in over 100 cities across North America participate in Canstruction, collecting millions of pounds of food for local food banks — the New York City show features local architectural and engineering talent. At the close of the competition, all of the food from the show will be donated to City Harvest.
See pictures of quite a few can sculptures at Eat Me Daily. My favorite is this scene from a recent movie you might recognize. Link
