MySpace LayoutsThe kaleidoscope is a toy containing small, brightly-colored tumbling objects, and a set of mirrors which reflect the view of the tumbling objects into repeating, symmetric patterns. The tumbling objects — typically coloured beads or pebbles — are enclosed in a transparent or translucent chamber mounted at one end of a tube; the viewer looks in the other end of the tube. Mounted lengthways along the inside of the tube are either two or three striplike mirrors which combine and form the image.If the mirrors are mounted at a 45° angle to each other, eight duplicate views are created. A 60° angle leads to six views, or 90° to four. As the object chamber is rotated, the tumbling of the objects within presents the viewer with an infinitely-varying succession of colors and patterns. Although the composition within one triangular cell of the view is arbitrary, the overall pattern is beautifully symmetric because of the reflections in the mirrors. A two-mirror model yields a single pattern isolated against a black background, while a three-mirror (closed triangle) model yields an infinitely-repeating pattern that seems to fill the entire field of view.Kaleidoscope tubes can be made inexpensively of cardboard, or elegantly out of brass, wood, or other fine materials. The tumbling objects can be beads, semiprecious stones, chips of glass, or almost any imaginable substance. Sometimes the object chamber is filled with liquid so that the items float and move in a more fluid manner. Some high-quality kaleidoscopes have lenses at one or both ends to gather light and/or sharpen the image.For a 2D symmetry group a kaleidoscopic point is a point of intersection of two or more lines of reflection symmetry. In the case of a discrete group the angle between consecutive lines is 180°/n for an integer n=2. At this point there are n lines of reflection symmetry, and the point is a center of n-fold rotational symmetry.The technical stuff from Wikipedia...

It's easy if you try
No hell below us
Above us only sky
Imagine all the people
Living for today...Imagine there's no countries
It isn't hard to do
Nothing to kill or die for
And no religion too
Imagine all the people
Living life in peace...You may say I'm a dreamer
But I'm not the only one
I hope someday you'll join us
And the world will be as oneImagine no possessions
I wonder if you can
No need for greed or hunger
A brotherhood of man
Imagine all the people
Sharing all the world...You may say I'm a dreamer
But I'm not the only one
