Rings of Saturn
Inventor Thomas Casey envisions a world in which there is an amusement park ride that combines the Ferris wheel with the merry-go-round. He calls it the "Rings of Saturn" and he's already gotten a patent on it. It's a crazy looking ride, and makes me a little nauseous just looking at it. It runs on a system of gears, but the center ring appears to jerk and lag a little bit when it's rotating. Hopefully if this thing ever gets made, they'll smooth that out.
