Spirographs quickly gained popularity because they allowed children (and adults) who didn’t think they had the artistic talent to create interesting designs.Now define the new (relative) system of coordinates ( X ′ , Y ′ ) {\displaystyle (X',Y')} with its origin at the center of C i {\displaystyle C_{i}} and its axes parallel to X {\displaystyle X} and Y {\displaystyle Y} . The much-loved toy from yesteryear has now been turned into a range of different sets ready to capture the imaginations of a whole new generation – it's safe to say that Spirograph is going to be sticking around (and around, and around) for a good while yet! While many will have played with it and produced some interesting patterns, and presumably also had a vague sense that some maths is happening, I suspect many won’t have thought about it too hard.

In your final illustration, I believe your 52- and 60-tooth patterns are swapped if the outer gear is the same throughout. The degree of the rotation tells you how many times you can do this before you’re just turning it all the way round (or, what fraction of 360 degrees the smallest angle you turn it through and get the same thing is).

Add to that, the gears and rings come in multiple shapes and sizes, so there really is no limit to the variety of patterns you can create. The first person we can look at is Johann Samuel Eberhardt, a Swiss mathematician who published a paper in 1843 titled “New and Useful Design for a Drawing Instrument. which introduced it to the United States market in 1966 and promoted it as a creative children's toy. Spirographs can produce a multitude of different interesting and intricate patterns, but did you know that these patterns have a special name?
