Kaleidoscope, c.1870s, By Jules Duboscq a Paris
David Brewster, creator of Brewster's Law, patented this device in 1817. It consisted of a long, hollow tube containing two glass mirrors running along the length of the tube and separated from each other at an angle of 60 degrees. Where mirrors converge there is an eyehole to see fragments of colored glass. When the tube is rotated these fragments shift position and different symmetrical patterns are seen.
