"Welcome to the New Dark Age," says a sinister little monster who looks like a swamp-colored cloud with feet. His multicolored doppelgangers bop up and down behind him, all of them projected on the wall of MOCA PDC's upstairs gallery. There, artist Ben Jones has installed projectors facing in four different directions. It's hard not to get in the way of the light and cast your shadow across a psychedelic sunset or against the morphing image of an alien. Despite the every-which-way activity, the whole show feels precise, like an arcadeful of games playing out perfectly without the help of players. 8687 Melrose Ave., W. Hlywd.; through Feb. 24.
