Kaleidoscopic

The kaleidoscope is an optical toy, where the user sees many beautiful, colourful patterns. It was invented in 1817 by Scottish physicist Sir David Brewster (December 11, 1781 – February 10, 1868). He also invented the binocular camera, the polyzonal lens and the lighthouse illuminator, as well as coming up with an improved version of the stereoscope applied to photography, which was the first portable, 3D viewing device.

The word "kaleidoscope" is derived from the Ancient Greek kalos, "beautiful, beauty", eidos, "that which is seen: form, shape" and skope, "to look to, to examine."
