Jen Stark cut a hole the shape of a water lily into the northernmost wall of Martha Otero gallery, then built up layer upon layer of carefully colored paper, each cut in the same plantlike shape but each smaller than the last. The result is a twisting vortex of color that gets narrower and narrower and finally disappears. The best works in Stark's current show are similar: powerful, precise, dimensional and mostly made of paper. 820 N. Fairfax Ave.; through Nov. 10. (323) 951-1068, marthaotero.com.
