Mark gets an arty no-prize that helps feed the homeless for bringing us Canstruction:

A foundation of the Society for Design Administration (SDA), Canstruction® is a design/build competition currently held in cities throughout North America. Teams of architects, engineers, and students mentored by these professionals, compete to design and build giant structures made entirely from full cans of food.

Don't miss the photo and video galleries! Puts those soda can displays at the grocery store to shame.
