The Simpsons Ride is a motion ride at Universal Studios Orlando.
You and 5 other riders enter a car inside the building. It seems like it will be a nice pleasant ride, but then Sideshow Bob takes over the ride and tries to kill you and your fellow riders. The car moves into a screening area where it looks like you are riding a rollercoaster. It's a 3D realistic screening. The car you are in moves around acting like you are actually experiencing what you are watching.
