CANstruction is the event; a yearly fundraiser for the SF Food Bank in which various SF landmarks are recreated out of donated cans of food.  The Transamerica Pyramid, Alcatraz, Sutro, MOMA, and Brian Wilson's beard all received the Campbell's treatment, while, surprisingly, San Francisco uber-landmarks the Golden Gate Bridge and New Mission Theater were left out.

Sadly, this year's exhibition has passed with very little press or fanfare, but pictures of these creations are starting to make their way online for anyone wishing to gawk at what they missed.
