KHALEIDOSCOPE

A kaleidoscope is a circle of mirrors containing loose, colored objects such as beads or pebbles and bits of glass. As the viewer looks into one end, light entering the other end creates a colorful pattern, due to the reflection off the mirrors. Coined in 1817 by Scottish inventor Sir David Brewster,[1] the word "kaleidoscope" is derived from the Ancient Greek καλ(ός) (beauty, beautiful), είδο(ς) (form, shape) and -σκόπιο (tool for examination)—hence "observer of beautiful forms."
