Kaleidoscope is a device based on the principal of multiple reflection. It consist of mirrors inciled to each other. The mirror form multiple images of object in front of them. This creates beautiful patterns which change when the kaleidoscope is rotated or shaken. Sir David Brewster invented it.

A kaleidoscope is an optical instrument with two or more reflecting surfaces tilted to each other in an angle, so that one or more (parts of) objects on one end of the mirrors are seen as a regular symmetrical pattern when viewed from the other end, due to repeated reflection. The reflectors (or mirrors) are usually enclosed in a tube, often containing on one end a cell with loose, colored pieces of glass or other transparent (and/or opaque) materials to be reflected into the viewed pattern. Rotation of the cell causes motion of the materials, resulting in an ever-changing viewed pattern.
