Marking its 10-year anniversary, the Petaluma Art Center opens 2018 with a group show, ‘Power of Ten: Scaling Up,’ that takes the art center into a new decade with innovative and thoughtful works in several mediums. Inspired by Charles and Ray Eames’ 1978 film, Powers of Ten, in which connections are made between the largest and smallest objects in the universe, the show is curated by Lisa Demetrios, granddaughter of the Eames, and presents paintings, photography, sculpture and even architecture that encompass themes of natural patterns and sustainability. The exhibit opens with an artist reception on Saturday, Jan. 20, at Petaluma Arts Center, 230 Lakeville St., Petaluma. 5pm. $5. 707.762.5600.
