Tapered Mirror Kaleidoscopes: hidden within these colorful tubes are tapered mirrors, 2 rolling glass spheres, and 1 dichroic glass reflector. These elements combine to produce the dynamic and magical images seen through the view window as the device is slightly tilted back and forth and brought in and out of a bright light source. The first design uses 3 mirrors to create the hexagonal symmetries, the second design uses 4 mirrors to produce the infinite cylinder effect. These unique teleidoscope designs are but two of many creations by artist Marc Tickle. Invented by the famous Scottish physicist Sir David Brewster (1781-1868), the kaleidoscope is an ultimate physics toy and entire field of artistic endeavor.
