Covered in local landmarks and colorful SF characters, Ruth Asawa's 1973 San Francisco Fountain captures the city's spirit. Sculptor Asawa used unconventional techniques: she collected favorite images of San Francisco from 250 people – famous artists to schoolchildren – sculpted them in bread dough, then cast them in bronze. Apple Inc. designed its flagship store for this spot, but there was a public outcry defending the fountain – so Apple eventually redesigned its building around it and restored the fountain.
