The concept begins with a visual association: The kaleidoscope, a cylinder with infinite possibilities. In the 19th century, nobody resisted the fascination of the kaleidoscope. This almost philosophical instrument was invented in 1816 by Scottish scientist Sir David Brewster in view of optical experiments. During the Belle Epoque the kaleidoscope became a true rage. In the Victorian salons the magical cilinder was a popular attraction. After supper, the choice of breathtaking kaleidoscopic images was a favorite pastime for the beau monde.
