this is the intricate kinetic sculpture of scott weaver, fabricated entirely of toothpicks sourced from all over the world. it is 35 years in the making, and still undergoing improvements (!!). entitled rolling through the bay, the sculpture consists of multiple "tours" through san francisco landmarks i.e. chinatown, the golden gate bridge, alcatraz, the castro district (rainbow toothpicks!), lombard street, etc.. just plain mind-blowing, and so beautiful...i can't even fathom the patience involved.
