What is Spirograph®?
Spirograph is a toy drawing that allows the user to draw patterns of cyclic curved lines. The original toy consisted of a series of templates and inserts that joined together using teeth, such as teeth of machine gears. The inserts were perforated with several holes for receiving a pen or pencil and holding the tool when moving the insert around the interior of the template would gradually shape the design when the pen watched its cyclic formula. The name Spirograph® is a registered trademark of the company Toy Company Hasbro, Inc. And it should be capitalized in a discussion of one of their Spirograph® toys. However, the word spirography was used before it became a trademark and also meant any such drawing or other similar facilities that create such patterns and become part of the English language as a noun and thus not always capitalized.
Origins SpirographHe returns as drawing toys to 1908, when a similar device called The Wondergraph, which used geometric drawings, sell Sears and Roebuck Co. Primarily a wooden device that contained a small record and wooden styles. The former facility also called Spirographs invented a French mathematician in the 80s of the 20th century, but it was primarily a mathematical tool for calculating an area included by certain types of curves than a toy. The first toy Spirograph® was sold by Kenner in the United States in 1966.
The original toy Spirograph consisted of stators and inserts that are lined with teeth, such as those on mechanical gears and designed so that the teeth of each insertion fit any stator. Stators are templates of different shapes that are placed on paper and should be stationary during the drawing process. Stators in the original toy Spirograph included small holes to be tuned to the basic tallyour carton or other surface with paper between.
Current versions use magnetic tablet and metal pins to hold the stator. The insert with one or more holes for some type of cartoon tool, such as a pen or pencil, is placed against a stator that can be several shapes and can receive inserts in and sometimes on the outside. By holding down the mining and against the stator and using the drawing tools to move around the stator, the geometric design of curved lines and a combination of drawing dishes, inserts and stators is possible to create almost endless variety of designs.
Today there are many derivative toys based on original spirituals and are sold under other names. In addition, in devices such as devices such as the principle of Spirograph®, which creates curves that can be described using mathematical functions and equal programmable laser projectors for stage lighting. These devices can trace the spirit of the spirographic patterns to the projectionm media like a scene smoke or screen.
