Gordon Bradt is behind some of the coolest kinetic sculptures we have seen. The Kinetico Studios Gordon Bradt Golfer & Skiier are fun sculptures that use a simple motor to generate motion. According to the company, 100k of these were produced between 1975 and 1985. The series included a golfer, tennis player, fisherman, jogger, skier, baseball player, hockey player, and a fencer.
In the above video, I tested the Gordon Bradt Golfer & Skiier. They are mechanically driven by electric clock motors. The figures are made of bronze with spring steel. These are rare but you can find them on eBay.
