Judith Schumacher is a sculptor. In a single room she has arduously and meticulously placed 983,000 small brass beads so as to cover the entire (and uneven) floor of the space. The unevenness prevents the perfect packing that physicists could predict as ideal; instead a form of chaos theory intervenes, complicating even further the obsessional and time-based quality of the work. Brass bearings of this kind are essential ingredients of landmines and other explosive devices.
