George Rickey's Space Churn with Squares (1969) is a quintessential example of the kinetic sculpture for which the artist earned international recognition. Developed during one of the most productive decades of his career, the work belongs to a sustained body of geometric, motion-driven constructions that established Rickey as a leading figure in kinetic art. His pieces are governed by wind and gravity rather than mechanical force—a philosophy fully expressed here.

The sculpture presents a diamond-oriented outer frame of polished stainless steel enclosing nested geometric elements—smaller squares suspended on carefully balanced axes within the larger form. Measuring 35½ × 20 × 13 inches, the piece represents an accessible scale for Rickey's oeuvre, well-suited to both private and institutional settings. The highly reflective surface shifts with changing light, while the suspended interior squares rotate slowly in response to the slightest air movement, continuously reconfiguring the composition.

Rickey's kinetic sculptures are held in the permanent collections of institutions including the Museum of Modern Art, the Hirshhorn Museum and Sculpture Garden, and the Tate Modern, affirming his enduring place in twentieth-century art history. Space Churn with Squares exemplifies the formal precision and quiet dynamism that have made his stainless steel constructions among the most recognized contributions to postwar sculpture.
