Tamar Ettun wants viewers to interact with her art. Don’t handle everything haphazardly, but consider your relationship to the photographs, sculptures, and videos currently on display at Transformer. The pieces in this exhibition are culled from the artist’s larger New York installation, “Performing Stillness,” and both shows invite viewers to think about which pieces are still and which generate movement. A plastic glove filled with plaster certainly looks motionless, but it’s bent as if grabbing something in a fist. A stringed instrument formed from a metal strainer and wooden rod doesn’t immediately indicate motion, but it can be picked up and strummed like those “guitars” kids make from rubber bands and tissue boxes. The goal, Ettun writes in her statement, is to “evoke the memories of a physical sensation or movement.” At the Transformer show, you’ll bend your mind and your body. The exhibition is on view Wednesdays through Saturdays noon to 6 p.m. to Oct. 25 at Transformer Gallery, 1404 P St. NW. Free. (202) 483-1102. transformerdc.org.
