Powered by gravity, counterweights, and springs, the tabletop sculptures of San Francisco artist Dan Grayber cling to concrete walls and climb up corners. Theyre like metal, mechanical spiders, delicately balanced and often displayed under glass. Its total guy art, like something from the pages of an old Popular Mechanics, with rubber tank treads and dangerous pointy parts, cams and pistons, cables, pulleys, and levers. But theyre also static, not truly robots, and incapable of movement. Theyve been perfectly positioned and locked into place. Touch one, or if a gallery wall shifted slightly out of alignment, and the hardware would collapse out its equipoise. Having been so intricately, painstakingly assembled, like modern-day ships-in-bottles, they only want to be left alone. However many hundreds of hours Grayber put into them, they dont need him any more. BRIAN MILLER
