One of my favorite rides at the amusement park is the Scrambler. The Scrambler has three long arms that revolve horizontally around a central post. At the end of each arm hangs a group of seats on which the "victims" sit. These seats revolve in a circle at the end of the arm (see fig. 1). The rider travels in a circle, which in turn is moving around a larger circle. I have always been intrigued by what the path the rider traverses really is— what it would look like from above. I have also wondered how the ride could be made more exciting.
