Spirographs require a certain degree of fine motor skill that children under the age of six are often lacking. Or from that set, using one of the shapes that isn’t circular, like the long thin extended one, or the rugby-ball shaped cog. The second one of these – where inside the small circle the pen-hole is – is also a bit more information than we need. The mathematician Bruno Abakanowicz invented a new Spirograph device between 1881 and 1900, which was used for calculating an area delimited by curves.That is, if you have two holes on the cog which are the same distance from the centre of the cog, they’ll both draw the same pattern, even if you start from the same place – again, it just might be rotated around, as you’ll be starting from a different point along the line. Spirographs can produce a multitude of different interesting and intricate patterns, but did you know that these patterns have a special name?

Spirographs quickly gained popularity because they allowed children (and adults) who didn’t think they had the artistic talent to create interesting designs.

The Travel Spirograph is a smaller, handheld Spirograph where all the bits and pieces are contained within the shell of the Spirograph itself. In your final illustration, I believe your 52- and 60-tooth patterns are swapped if the outer gear is the same throughout.
