Spirograph is still sold today. In 2013, the brand was re-launched in the US by Kahootz Toys – although the design has been revised over the years, the current version essentially functions as it did nearly 50 years earlier.
For the technically minded – Spirograph produces mathematical roulette curves of the variety known as hypotrochoids and epitrochoids. For everyone else, it makes cool designs.
There’s a Facebook Spirograph Art Community
