I didn't know I liked group exhibition "Time and Material" until I'd left. It feels unfinished. You're not sure if you're supposed to step past Sam Falls' big green tarp into the gallery space or stare down at Kyle Thurman's enamel-topped tables. But in the small back room, Joe Zorrilla's video shows slices of a white frosted cake awkwardly removed and then replaced in different spots over and over. The cake's never complete or consumed, which strikes me as a really accessible way of talking about indeterminacy. M+B, 612 N. Almont Drive, Beverly Hills; through Dec. 22. (310) 550-0050; mbart.com.
