151 Parts to Infinity

Mathematician and sculptor Dr. Helaman Ferguson, PhD, worked with Danko Arlington Inc., a Baltimore job shop specializing in aluminum and bronze sand castings, to create a towering sculpture, the Umbilic Torus SC, with infinite lines. The silicon bronze castings for the outer shape of the piece were produced without pattern tooling. New Arts Foundry, Baltimore, welded the finished piece together as an assembly that weighs more than 20,000 lbs. The total weight of the sculpture is approximately 65 tons.
