so my Wild Gears arrived from Canada and the possibilities and math is mind boggling. Definitely a learning curve there for the doughnuts to make parallel lines and the gears within the gears. I chose birch over acrylic and love the scent of the wood.

See also the second-order roulette (or gear-in-hoop-in-wheel #spirograph) made possible using #WildGears:

Especially Glagolj's survey and analysis https://glagolj.github.io/gg-blog/
and their simulation tool: https://glagolj.github.io/gg-blog/tools/roulette_plot.html

> #Spirograph is a fond #toy for many people. But the result is soon exhausted, unless one starts to combine lines from different setups.
> In the last decade #AaronBleackley managed to invigorate things with new geared toys called #WildGears.
> The #WildGears are produced with high precision and it is possible to use 3 elements in a gear-in-hoop-in-wheel combo that produces intriguing shapes on paper.
