George Rickey devoted his career to investigating the poetic possibilities of movement. In his words, “Control of weight and balance—and also time—gives me a means of expression comparable to color for a painter or sound for a composer.” Triple N Gyratory III is an example of kinetic art, or art with moving parts. Each of the sculpture’s three N-shaped elements is so carefully counterweighted and balanced on ball bearings that even a gentle breeze will set it in motion. This introduces the element of random chance in the sculpture’s movement. When all “N”s move simultaneously, the resulting pattern is visually compelling, even meditative.
