"Snake Ceiling," by Chinese artist Ai Weiwei, is pictured at the Mori Art Museum in Tokyo in 2009. The work is part of Ai's first major U.S. art exhibition, scheduled for launch at Washington's Hirshhorn Museum on Saturday. The show, "Ai Weiwei: According to What?", groups sculpture, photography, video, audio and installation work.
