A house of mirrors or hall of mirrors is a traitional attraction at funfairs (carnivals) and amusement parks. The basic concept behind a house of mirrors is to be a maze-like puzzle, but in addition to confounding the spatial senses with a labyrinth element, the visual senses are also confounded by the construction of the walls of the maze of optically reflective material, most often glass mirrors. Sometimes each mirror may be distorted into different curved, convex or concave shapes to give the participants unusual and confusing reflections of themselves.
