Jim Denevan’s mission was to create the world’s largest work of art. His canvas? The world’s largest lake. Jim and his team decorated 9 square miles of the frozen Siberian lake with circles based on the Fibonacci sequence. The result is, in a way, less impressive than the process. Crew members had to brave sub-zero temperatures and hurricane-force winds. Some of the gusts were so strong, they actually blew away the art work. The project was recorded in a documentary and book.
