stabile

His brightly colored twisting mobiles and gracefully hulking stabiles made him a titan of 20th-century art, often imitated but never equaled.

His design included a stabile — a stationary work for the floor — and, suspended from the ceiling, one of his signature mobiles, its gentle rotation powered by a motor.

“Nonspace” includes both mobiles — the term coined in 1931 by Marcel Duchamp to describe Calder’s kinetic sculptures that move in response to air currents and gravity — as well as their static cousins, stabiles.

The award itself, the “Ellie,” is modeled on the “Elephant” stabile sculpture, designed by acclaimed American artist Alexander Calder.

Jon Kessler, usually Mr. Mechanical, has three new pieces that are essentially airy stabiles dangling sweet found objects, as if they were collaborations by Calder and Dalí.
