In San Geronimo, two monumental vertebrate obelisks stand sentinel in front of the home of sculptor, performance artist and professor Nathan Lynch. Scattered in their glossy presence are dozens more. Puffed-up podiums and deflated, cratered soap boxes, a 5-foot-tall drooping trophy, bathtubs with ceramic bubbles at their feet and an army of amorphous blobs that look equal parts Dr. Seuss and David Cronenberg—wherever one stands, it feels a bit like being inside a cartoon.
