One fixed sculpture of black pieces hanging on wires. Nothing moves; you do. From point A the pieces close into Leonard Cohen. Walk a quarter of the way round the room to point B and the very same pieces close into Bob Dylan.
Each piece is a solid whose shadow from A is a fragment of Cohen and whose shadow from B is a fragment of Dylan. The sculpture is the space both portraits agree on, cut apart along planes that neither eye can see along, so from either point the cuts vanish. Everything you see is drawn live by shaders. The first anamorphosis does it the other way, with plates that turn.
