This series of sculptures, which began in 1980, initially used both the wall and floor as support surfaces, presenting a 180° experience that emphasized side and three-quarter views. The pieces explicitly focused attention on gravity and support as they incorporated the surrounding architectural space of the wall and floor. The series continued into the 1990s with free-standing sculptures that utilized planar surfaces within a given sculpture that functioned as wall or floor. The work evolved to focus particularly on a viewer’s likely movement through space, over time.
