Installation: A changing environment in which many elements, seen or unseen, have an effect. These invisible relationships can be perceived between the 233 spheres when a visitor triggers the solenoids and the motions become patterned.  The amount of movement within the field of the spheres is determined partly by the real-time intensity of solar surface activity and partly by numbers of people: When there is sufficient energy, groups of spheres will ‘lock’ into a new orientation.  The whole field can be seen within, and be affected by, each sphere. 233 acrylic spheres; paint; acrylic blades; Neodymium magnets; solenoids; control system; antenna and receiver 12m x 4m x 4m
