There is little doubt about the mechanical ingenuity or scientific impact of Snelson's work. But is it also art? Absolutely. His sculptures are pure outpourings of creative energy, utterly useless as objects and yet visually arresting. Viewers can admire their beauty and elegance in parks and plazas from Japan to Germany, where local governments, corporations, and collectors have invited Snelson to install his work. Snelson may not get a critical turnout these days, but his sculptures have quietly entered the collective visual imagination.
