The Brewster Kaleidoscope Society is an international organization for kaleidoscope enthusiasts.

Named after the inventor of the kaleidoscope, Sir David Brewster, its purpose is to provide a forum for artists, collectors and retailers to promote and perpetuate kaleidoscopes as an art form. It serves as a network linking kaleidoscope artists, collectors, and retailers. Membership benefits include a quarterly newsletter, an annual convention, class, and much more.

There is a remarkable camaraderie among the caring and sharing members of this unique organization, and active members agree that the biggest benefit of all is the strong bonding and close friendships that are formed.
