This four day International Expo brings together kaleidoscope designers, artists, retailers, and collectors from around the world. The Expo will feature classes, talks, demonstrations and a huge kaleidoscope showroom. Over fifty artists will be displaying more than 1000 originally designed kaleidoscopes for viewing and purchase. Participants will also experience a unique exhibit of over 50 stunning and seldom seen kaleidoscopes from a private collection. The general public will be encouraged to join the members and artists the Kaleidoscope Art Expo on Saturday and Sunday. One of the major goals of the Expo is to provide an opportunity for those who may be new to, or have limited familiarity with, kaleidoscopes to gain a better understanding of the combination of art and science that is represented in every kaleidoscope that is created by talented artists. A historic retrospective of classic kaleidoscopes will also help develop understanding of the artistic nature of the kaleidoscope.
