It's more than just a ferris wheel! The Sun Wheel is very cool. If you look at the picture you'll notice that some of the gondolas aren't around the outside. Those ones are on eliptical tracks the go from the outside of the wheel toward the centre, and as the wheel turns your gondola moves along the tracks. As you can see you don't get as high up as the red stationary gondolas, but you do get a very interesting ride.
