House of mirrors (Theme park attraction)

A house of mirrors or hall of mirrors is a traditional attraction at funfairs (carnivals) and amusement parks. The basic concept behind a house of mirrors is to be a maze-like puzzle. In addition to the maze, participants are also given mirrors as obstacles, and glass panes to parts of the maze they cannot yet get to. Sometimes the mirrors may be distorted because of different curves, convex, or concave in the glass to give the participants unusual and confusing reflections of themselves, some humorous and others frightening.
