[...] Stout this month published "Horizontal Skyscraper," Holl's slender but sumptuous monograph on his firm's Vanke Center in China, a five-story structure perched on eight legs that is as long as the Empire State Building is tall. With condominiums, a hotel and offices inside, it branches across and above a lush landscape that includes cafes set in artificial hillocks, but also functions as part of the larger community's storm-water management system. The "Etrog Box," used during the festival of Sukkot to hold a lemon-like fruit, looks like an egg spun from silver netting; the "Challah Cover" - which is put over bread before it is blessed on the Sabbath - could be woven strands of pastry. The exhibition will be at the museum at 736 Mission St. through October. [...] yes, replicas of three of the objects can be purchased in the gift shop. [...] while any critique of mine is months away - students won't start class until summer session - the prow facing Chinatown shines with a taut cloak of sun-deflecting fins across glass, with just enough variation up and across to keep things from being static.
