Ai Weiwei, the Beijing-based artist and activist, is known for stirring the proverbial pot. He is also famous for destroying one—an ancient Han-dynasty urn that he allowed to ceremoniously fall from his hands and shatter into pieces. A 1995 photographic triptych documenting that provocation (above) is one of some 40 works on display in Ai’s first U.S. survey, at Washington, D.C.’s Hirshhorn Museum and Sculpture Garden. Called “Ai Weiwei: According to What?,” the show expands on his 2009 blockbuster retrospective in Tokyo and runs from October 7, 2012, to February 24, 2013. hirshhorn.si.edu
