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,, 4 pm–midnight, free before 7 pm/$5 after. Also Sun Jan 29, noon–7 pm, free)
