What is a 4D?

Please don't yell at me, but exactly what is a 4d coaster, how does it work, and where is one?

4D is a new Arrow Dynamics concept. The seats flips head-over-heels as the train navigates the track. The train rides on four rails instead of two. 2 rails acts normal; guiding the train, and the other 2 (which vary the distance from the guide rails) control the motion of the seats. Located at Six Flags Magic Mountain. The coaster is called X.
