Zachary Coffin "Rockspinner6" Kinetic Sculpture

From the exhibition Sculpture in Motion at the Atlanta Botanical Garden on view through October 2008 and curated by Brigitte Micmacker from Sculpturesite Gallery. Curator's commentary: "Zac Coffin's interactive installations emphasize the tension created by testing the limits of the laws of physics by presenting seemingly impossible gravitational situations. In Rockspinner 6, Coffin first found the exact center of gravity of a magnificent five-ton granite boulder (quarried near Atlanta), inset an extremely low-friction bearing, and installed it atop a minimal but sturdy stainless steel shaft. The resulting ten-foot tall sculpture can be sent into a spin by a small child, and continue its completely silent rotation for a stunning length of time, due to the force of inertia and the use of an ultra-lightweight lubricant. Yet, the highly specialized technology is hidden here as the massive monolith connects the viewer with quintessential nature." A solar collector also enables the sculpture to spin slowly without interaction.
