Tom Longtin, Trefoil Knots

Trefoil Knots is a cast concrete sculpture (really a pendant pair of sculptures with opposite chiralities) by Tom Longtin, who passed away in late May. Tom combined a deep interest and knowledge of engineering, mathematics, and technology with an insatiable creative spirit. His sculptures, which often explored the mathematical complexity of geometric forms, especially never-ending knots, have been exhibited both locally and internationally.
