A Madhouse is a flat ride usually manufactured by Vekoma. A similar attraction under the name Mystery Swing is created by Mack Rides. The ride is designed to be an optical and physical illusion, consisting of several rows of seats attached to a swaying gondola within a rotating drum. The ride creates the impression that the rider is turning upside down, whereas it is actually the room that is moving around them.

Efteling is a fantasy-themed amusement park in Kaatsheuvel, the Netherlands. The attractions reflect elements from ancient myths and legends, fairy tales, fables, and folklore.
