Another beautiful and beautifully odd show from Tom Sachs: Space Program: Europa at the Yerba Buena Center for the Arts in San Francisco. It's the second one of his Space Program exhibitions we've visited (the first was Mars at the Park Avenue Armory in New York), though this time we missed the demonstration that brings the whole show to life. Still, with the blatant tribute to the beauty of the obviously handmade (and to the act of hand-making) and its joyous serious silliness, even inanimate this work is lively. Above, Bonsai, in bronze, molded from, yes, Q-tips, toothbrushes and tampon tubes.
