Scott Weaver's amazing piece, made with over 100,000 toothpicks over the course of 35 years, is a depiction of San Francisco, with multiple ball runs that allow you to go on "tours" of different parts of the city. It will be on display in the Tinkering Studio until June 19th! http://tinkering.exploratorium.edumoreless
