mobile (mōˈbēl) [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.
