There's a Man Ray, Duchamp & Picabia exhibition @ Tate Modern. I went on Tuesday - it's bl00dy brilliant. I know a bit about Man Ray's stuff but the three artists work together makes for a great show. Funny, sexy, inventive - they collaborated effectively and it really shows - the Tate Modern has pulled off a belter and no mistake.
I'm not sponsored by them - honest - just go see it
