The Kaleidoscope was invented in 1816 by Scottish scientist,
Sir David Brewster.
Brewster named his invention after the Greek words kalos or beautiful,
eidos or form and scopos or watcher.
So kaleidoscope means the beautiful form watcher.

Brewster's kaleidoscope was a tube containing loose pieces of colored glass and other pretty objects, reflected by mirrors set at angles. They created patterns when viewed through the end of the tube.
