The free-ranging title of this show at Chandra Cerrito Contemporary could well refer to the wide-open playing field of contemporary art. Zachary Royer Scholz's prints, sculptures, and installations derive from and combine abstraction, postminimalism, and conceptual art. "35474708" (I've abbreviated the lengthy titles) is a playpen-size square enclosure made of steel shelves stacked like logs in a frontier stockade. "27769408" suggests a gigantic square picture frame mat leaned against the wall; it's actually a sandwich of latex paint layers an eighth-inch thick (the bottom half) rotated down as if hinged from the groove in the wall from which they were razored and peeled (the top half). "3710611308" transforms the gallery stairs into art with strips of tape placed on the risers. "2265308" is a floral-themed diptych reminiscent of De Feo's "The Rose" -- but, made of carved foam, considerably more portable. Open Space runs through January 31 at Chandra Cerrito Contemporary (25 Grand Ave., Oakland).ChandraCerrito.com/ccc or 415-577-7537.
