Spirograph.

Spirograph is a geometric drawing device that produces hypotrochoids and epitrochoids, which are varieties of roulette curves.

It was developed by British engineer Denys Fisher and first sold in 1965.

The name has been a registered trademark of Hasbro Inc. since 1998 following purchase of the company that had acquired the Denys Fisher company.

The Spirograph brand was relaunched with original product configurations in the USA in 2013 by Kahootz Toys and in Europe by Goldfish and Bison.
