If you want to see some of the other patterns I made, you can check out my etsy shop A few technical details for those curious... I didn’t really mention the software/firmware flow. Basically, the designs I create can be represented via mathematical formulas/algorithms. I use python to generate 2 outputs, one with all the nail locations and one with the path to take. The software then takes this inf
