Detail of the Shalechet ("Fallen Leaves") installation by Menashe Kadishman of Tel Aviv, c.1998. Occupying a corner space called the "Memory Void," it consists of 10,000 iron faces strewn thickly across the floor. The faces are coarsely stamped but full of expression, with mouths open in suffering. Visitors are permitted to walk on the work. Doing so creates a loud, "industrial" noise and is quite a unique and moving experience. Jewish Museum, Berlin, Germany.
