[1] Introduction: What is Kinetic Art?

A work of art that has movement or parts that are set in motion. The movement may be real or imagined. Movement may be mechanically powered (for example, by electricity, or air or water motion), or produced by the viewer moving past a work, or the work given the illusion of movement, such as op art, which appears to flicker. Kinetic art sometimes merges with other types of avant-garde art, including performance art, computer-generated art, mixed media, and Installation art. Leading kinetic artists include Alexander Calder, Bridget Riley, and Nam June Paik.
