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 Eoin Cussen, 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.”
