Description

This kaleidoscope is generated from my fractal named Crosshatch and would look great in a grouping.
From Wikipedia:
A kaleidoscope is a cylinder with mirrors containing loose, colored objects such as beads or pebbles and bits of glass. As the viewer looks into one end, light entering the other creates a colorful pattern, due to the reflection off of the mirrors. Coined in 1817 by Scottish inventor Sir David Brewster,[1] "kaleidoscope" is derived from the Ancient Greek καλός (kalos), "beautiful, beauty",[2] εἶδος (eidos), "that which is seen: form, shape"[3] and σκοπέω (skopeō), "to look to, to examine",[4] hence "observation of beautiful forms." [5]

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 set at 60� to each other so that they form an equilateral 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 colored objects presents varying colors 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.
