kinetic sculpture

Sculpture in which movement (as of a motor-driven part or a changing electronic image) is a basic element. Actual movement became an important aspect of sculpture in the 20th century. Pioneers such as Naum Gabo, Marcel Duchamp, L, and Alexander Calder produced movement by such means as water, mechanical devices, and air currents (as in Calder's mobiles). Neo-Dadaist works such as Jean Tinguely's self-destructing Homage to New York (1960) embody the concept of a sculpture that functions as both an object and an event—a “happening.”
