The Simpsons Ride is a motion ride at Universal Studios Orlando.
You and 5 other riders enter a car inside the building. It seems as it will be a nice pleasent 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 expieriencing what you are watching.
