A great childhood toy (I was always very jealous of my sister who owned this and wouldn’t let me play!)
Spirograph is a geometric drawing toy that produces mathematical curves of the variety technically known as hypotrochoids and epitrochoids. A Spirograph consists of a set of plastic gears and other shapes such as rings, triangles, or straight bars.
It could be used for art presentations or to show mathematical calculations. You could also print it off and use it for colouring in.
