These sculptures are part of "Canstruction" a nonprofit organization that holds annual design and build competitions to construct fantastic, giant sized, structures made entirely out of canned food. In each city after the structures are built and the winners declared the creations go on view to the general public as giant art exhibits. At the close of the competitions all of the food used in the structures is donated to the local food banks for distribution to community emergency feeding programs.
Canstruction raised over 2 million pounds of food in 2010 which was donated to local food banks, enough food to provide 1.5 million meals.
An interesting way to have fun and help to people in need.link
