I am looking to make a snowboarding birthday cake. I need to make it move whether it be the snowboarder, chairlift ..etc. I want to make it as simple as possible. I've thought about tying a rope of some sort and pulling slowly to move the snowboarder down a hill, I've also tried to think of a way to make the snowboarder "jump" up onto a rail and grind as they do in real life...any suggestions on where to get moving parts or how I can make this work would be appreciated!! Thanks in advance
