Jeppe Hein challenges the traditional idea that the visitor is a passive figure, silently contemplating the work of art. He makes us participants, willingly or not. Rotating Labyrinth (2007) is a mirrored theatre in the round, whose exterior surface reflects the surrounding artworks and architecture. When you step inside, the curved walls gradually align so that the rest of the gallery space is obscured. Surrounded by mirrors, you become at once actor and audience, viewer and viewed, and your reflected image is simultaneously fractured and multiplied. As a further twist, the slow rotation of the curved walls means that you leave the work from a different part of the space to the one you entered.
