My girlfriend and I visited the Zimmeli Art Museum this afternoon. It was really great. The museum has an outstanding collection of art by Soviet dissidents. The works really give a sense of how oppressive it was to live in the former Soviet Union. There is also currently a special exhibition on "hyperrealism" -- a style of art done by dissidents to satirize the Soviet regime. Even if you're not especially interested in art, a half hour there might prove very enjoyable. And, at least right now, the museum is free. It's one of the best college art museums around.
