A Kaleidoscope operates on the principle of multiple reflection, where several mirrors are placed at an angle to one another, usually 60�. Typically there are three rectangular mirrors. Setting the mirrors at a 60�so that they form a triangle. The 60� angle creates seven duplicate images of the objects, five at 60�, and 2 at 90�. As the tube is rotated, the tumbling of the coloured objects presents varying colours and patterns. Arbitrary patterns shows up as a beautiful symmetrical pattern created by the reflections. A two-mirror kaleidoscope yields a pattern or patterns isolated against a solid black background, while the three-mirror (closed triangle) type yields a pattern that fills the entire field. For a deeper discussion see: reflection symmetry.
Modern kaleidoscopes are made of brass tubes, stained glass, wood, steel, gourds or almost any material an artist can use. The part containing objects to be viewed is called the 'object chamber' or 'object cell'. Object cells may contain almost any material. Sometimes the object cell is filled with a liquid so the items float and move through the object cell in response to a slight movement from the viewer.
