Attention and behold: Marcel Duchamp... as a lady! Or, not exactly. This is more than just a giddy Surrealist in a pretty hat and a little rouge. This is Rrose Sélavy, Duchamp's alter-ego with her own look, her own mind, even her own body of work. Sometimes artists create more than paintings and sculptures -- they create people. They form whole other identities, personas. Let's meet classic alter-egos from art history and contemporary performance practice. Be warned: Gender-bending, age-regression, metamorphosing, and dimension-crossing may occur.
