The Tinkering Studio website from the Exploratorium in San Francisco is billed as "Experiments with art, science, technology, and delightful ideas." It does not disappoint, and visitors may wish to make a special trip to San Francisco to see the Exploratorium in action after some time on the site. A good place to start is the Artists area. Visitors can learn about artists who've been inspired by the Tinkering Studio, such as Ana Serrano, who works with discarded cardboard and Andrew Lyndon, an Oakland-based videographer and animator. Visitors young and old must visit the Activities section as well. Here they can learn about marble machines, circuit boards, and light painting. Finally, interested parties shouldn't miss the site's fun blog, which includes entries on how to make your own potato head toy at home.
