Images repeat in Liz Walsh's show "Shadow Force," up now at the newly opened, artist-run Last Projects. You see the same weird, ghostly psychedelic group in the print on the far wall and in the game-like, animated video playing in the monitor above the little table that holds the press release. You see the same patterns on the monitor as you do in the yarn samplers Walsh has hung on the wall. But there's no consistency in the polish. Sometimes, images and patterns are crisp; sometimes they're slapdash. It's as if Walsh is willing to be slick when the urge hits, and sloppy when she just doesn't feel like caring or overworking. 6546 Hollywood Blvd., Ste. 215, Hlywd.; through Sept. 11.
