Confining Infinity
Limits of Infinity III by John Safer. George Washington University, Washington, D.C., 2000.
"I carved the interior shape while groping for a shape which would seem fulfilling, internally harmonious, and perhaps inspiring," John Safer explained. "When that part of the sculpture was complete, I realized that it was a three-dimensional rendition of the symbol for infinity. Safer chose to orient his sculpture vertically rather than horizontally and mounted it within an elliptical frame--in effect, confining infinity.
