Seattle artist Shawn Patrick Landis built a backyard inside the gallery: a wood fence, a fire pit, a grill, a folding chair, a parked motorcycle. Each component wears an inflated transparent box stuck to its side like a growth. A thicket of big, wormy inflation tubes gums up the scene, making you walk carefully through the alien setting. Each box is a thought bubble whose contents are open to interpretation. (Gallery4Culture, 101 Prefontaine Pl S, 296-8674. 9 am–5 pm, free.)
