Rolling Stones Gantry

Each member of the Rolling Stones — Jagger, Richards, Watts, Wood — is a magnetic bar, suspended in the air to the upper left like a rack of 4″x8″x48″ slugs of lead. Presumably some sort of internal coil winding, but not accurate to say giant guitar pickups. With an invisible gantry, they can be re-positioned, shifted from inside to outside. That distinction is crucial.
