Young Brunette Girl In The Bed With A Wall Mirror

Mirrors are employed in kaleidoscopes, personal entertainment devices invented in Scotland by Sir David Brewster.
Mirrors are often used in magic to create an illusion. One effect is called Pepper's ghost.
Mirror mazes, often found in amusement parks as well, contain large numbers of mirrors and sheets of glass. The idea is to navigate the disorientating array without bumping into the walls. Mirrors in attractions like this are often made of plexiglass as to assure that they do not break.
