The video was created by the production studio Virtual Republic. On their Vimeo page, they explain, "The notes and bars were exactly synchronised with the progression in the animation so that the typical movements of a rollercoaster ride match the dramatic composition of the music." Below is an interesting video about the making of the animation, which traces the forms of actual roller coaster tracks. For more information about the process, see Virtual Republic's Vimeo page.
