I've been meaning to do a post on David C. Roy's kinetic sculptures for a long time. I found him by accident when I was looking for something else, and was captivated by his combination of precision, mathematical engineering, and sheer beauty.
Each one is spring-driven and runs for an average of 20 hours. They are delicately carved from lovely, highly-polished, different-colored woods, and the best ones create the most marvelous moire illusions with their movements. One feels one could sit and contemplate their mesmerizing, shadow-theatre shapes for hours.
Mr. Roy, who has a degree in physics and engineering, says that the artistic influence of his wife, and later, an interest in optical patterns, led him to the designs he produces today. The names of his sculptures, words such as Radiance, Illusion, Spectrum, and Harmony seem to imply a dual interest in physics and metaphysics, or at least meditation, on Mr. Roy's part.
Interestingly, I thought these objects were small, either hand-held or head-sized; but if you look at Mr. Roy's About the Artist page, you will see that they are actually quite large, some of them about the size of large wagon wheels.
It's nice to see an elegant combination of craftsmanship and mechanical works; and combined, they produce a contemplative and, in some cases, satisfyingly clockpunk result.
