Calder designed this monumental sculpture especially for Princeton. For a short time the disks were painted orange to honor Princeton’s colors, but the artist gave instructions to have them blackened after his visit to campus in 1971. Most famous for his kinetic sculptures, or "mobiles," he also imbued his stationary "stabiles" (a term suggested by the artist Hans Arp) with a sense of movement and lightness.
