Corin Hewitt's performances have been called photography machines. Weavings stems from a 2007 performance in Portland. Using four cameras, fabrics, an image of a Native American basket, food, and Plasticine, Hewitt has made pictures of the basket photo, the patterned fabrics, a basket he made out of pasta, himself eating the pasta, a weaving made of Plasticine, a weaving made of beans, half-eaten food, the cameras themselves. No material is let go without commemoration. It makes you feel better about being a living thing. (Seattle Art Museum, 1300 First Ave, 654-3100. 10 am–5 pm, $15 suggested.)
