The Spirograph is a geometric drawing toy that produces mathematical curves known as hypotrochoids and epitrochoids. It was developed by British engineer Denys Fisher.

Fisher first exhibited the Spirograph in 1965 at the Nuremberg International Toy Fair and produced it in Britain. Kenner, Inc., acquired U.S. distribution rights, introducing it in this country in 1966 as a creative toy for drawing "a million marvelous patterns."

Hasbro Hasbro has marketed a variety of sets over the years. Toy company Kahootz also sells updated versions of the original Spirograph sets, including a deluxe set and travel versions.

The set created the most elaborate patterns of swirls and shapes. The Spirograph found its market among budding artists or their parents. It was dubbed the Toy of the Year for 1967 and attracted the eye of the Kenner toy conglomerate. The toy remains popular.

INTRODUCTION The basic spirograph set includes numerous circular discs and annuli. To construct a spirograph design, a pencil or pen is placed in one of a number of perfora- tions on a disc, and a pattern is traced as the disc rolls around a fixed annulus.

hypocycloid In that case, the shape it draws is called a hypocycloid – a set of curves which bounce off the outside edge of the circle, moving in towards the middle then back out to the edge. These shapes look like curved pointed stars.
