In an effort to implicate a wider public in the experience and production of art, Carsten H ller employs strategies of direct involvement that help to abolish the barrier between the work of art and the spectator. Sculptures and installations designed for the Fondazione Prada insist on visitor interaction, and the act is reciprocated: the works change progressively through intermittent lights that transmit vibrations to the visitor's body. A hallucinatory subversion of private sensation results, in accord with H ller's aspiration to sabotage the complacencies of everyday life. Complete with a biography and bibliography, this catalogue is the most exhaustive documentation of H ller's challenging work to date.
