As part of the Tate Modern's forthcoming exhibition Pop Life: Art in a Material World, the London museum is recreating a 1992 performance/installation. Identical twins will sit for the entire exhibition, October 1, 2009 to January 17, 2010, below a pair of identical Hirst "spot" paintings. That's a long time, so the Tate Modern is seeking twins to sign up.
