23. Charlie Callahan
West Marin painter and installation artist Charlie Callahan has depicted the urchin in his work for 20 years from Chelsea to Tokyo and back again. In reflection of the changing times, the October sun inspired this urchin emblem, a staple of an ongoing mandala series known as SEELIFE. Urchins have survived mass extinctions, and perhaps will assist in steering us away from global shipwrecks in the future.
