Since 2001, Michigan-based artist David Zinn has created scores of chalk drawings on the sidewalks of his home town Ann Arbor. David’s temporary street art is composed entirely of chalk, charcoal and found objects, and is always improvised on location. One of his most recognizable characters is Sluggo – an odd, green slug-like alien creature and the The Flying Pig that routinely appears on his doodles. David Zinn makes his chalk cartoon charactera come to life, giving them an almost three dimensional appearance as they interact with their surroundings.

Most of these drawings have appeared on sidewalks in Ann Arbor and elsewhere in Michigan, but some have surfaced as far away as subway platforms in Manhattan and construction debris in the Sonoran Desert.
