mobile mō´bēl [key], a type of moving sculptural artwork developed by Alexander Calder in 1932 and named by Marcel Duchamp . Often constructed of colored metal pieces connected by wires or rods, the mobile has moving parts that are sensitive to a breeze or light touch; it can be designed to hang from the ceiling or stand free on the floor. Mobiles became popular in the 1950s for interior decoration.
