There should be a whole strain of poetry devoted to the lifeguard tower, its spindly architecture propped all the way up there. They're often photographed in romantic shadow, against a setting sun. But L.A. photographer Amir Zaki looks baldly at them, these irregular objects just hanging in the sky. He's digitally manipulated them, but you'd be hard-pressed to say exactly how. Sometimes they glow and face up to the sun like Californians. Sometimes it's foggy and they are spaceships. Sometimes it's gray and cloudy, and they may as well be miniatures marooned in the corner of a Russian factory in winter. (James Harris Gallery, 312 Second Ave S, 903-6220. 11 am–5 pm, free.)
