If you haven’t seen enough altars to last a lifetime, you weren’t looking at art in the ‘80s. But Peter Hopkins’ new works make the form fresh. The tripartite panel paintings are hinged like medieval icons. If, seduced by the glamorous exterior, you swing one open, you’re hit with retina-blasting color. Divine energy, indeed. Only one more week to see them at Christopher Grimes Gallery in Santa Monica through August 31.
