Musical Roller Coaster

An animation that takes a roller coaster through a musical score, with symphonic music: http://www.diretodoforno.com.br/zko-roller-coaster. It appears to be an advertisement for a Chamber Orchestra in Zurich (Zürcher Kammer Orchester), produced by an ad agency called Euro RSCG Zurique. It would have been better if the notation actually reflected the music the whole time, but you can't have it all.
