As far as flat rides go, Delirium is one of the best. Essentially it's a pendulum on steroids. You can see from the screenshots just how far this thing swings and the circle of seats at the end of the pendulum arm spins while the arm is swinging. (137 feet up at 8 revolutions per minute) The ride is a Giant Frisbee by Huss. If you can find one of these it's definitely worth a ride.
