Zachary Coffin has been building large-scale kinetic and interactive sculpture for over 25 years. His work explores the boundary between art and viewer and the way humans can interact with a large mass in motion. His work draws from engineering and the history of industry for a visual language that is practical and dramatic yet unadorned. He has received multiple public and private commissions throughout the United States and Europe.
