Shot from multiple angles in a camera-lined studio, Prego's stop-action video shows a mini-explosion hanging in the air like a tuft of poisoned cotton candy, now red, now yellow, both volatile and arrested. The vantage point whirls around the plume at sick-making speed; the fire's very prettiness makes it sinister. Prego shot his second (and less successful) video, an allusion to Tarkovsky's "Solyaris," in Tokyo, focusing on freeway ramps and office towers indistinguishable from those in any other megacity. The show's third component, a pair of florescent tubes on rotating arms, borrows mad-clown techniques from Bruce Nauman. Through Feb. 10 (Lehmann Maupin, 540 W. 26th St. 212-255-2923.)
