Around this time of year, the average person in Seattle craves light with an intensity approaching the sexual. Three artist-curators want to give it to you: Susan Robb, Sierra Stinson, and Jim Demetre have organized ONN/OF, an entire weekend of art, performance, installation, projection, music, food, drink, and workshops, all involving sweet, sweet light. The list of participating artists is all-star, including Claude Zervas, Katy Stone, Rebecca Cummins, Maikoiyo Alley-Barnes, Rodrigo Valenzuela, Emily Pothast, No Touching Ground, Dumb Eyes… and we could go way on. Let your pupils shrink for once this winter. (The Sweater Factory, 1415 NW 52nd St, www.onnof.us, 4 pm–midnight, free before 7 pm/$5 after. Also Sun Jan 29, noon–7 pm, free)
