The GP Ice Race is a celebration of motoring in the most charming and pure way possible – manufacturers, professionals, and amateurs come here to drive around a man-made ice track and purposefully link lose just enough traction to make it daring link and sporty while maintaining just enough control to be safe. Sometimes they're even towing skiers behind them at speeds that approach the triple digits, a link sport called skijoring.

It's quite similar says Seltzer belying the complexities of modifying the design. "You have a lever which is in contact with a snail or a cam in the center on the minute wheel. And it takes the power draws it over the hour and once link per hour it falls and strikes a star in the center pushing it one link step forward and moving the jumping disc. So I had an idea. Why link don't we take this lever and instead of hitting the star we can strike a sound spring to make this nice gong effect"
