I signed up to be Secret Santa for a 7 year old kid, and his letter included a couple of drawings, he asked for colored pencils, and I thought back to my childhood and the fun I had with the spirograph, I searched and didn't find quite what I was looking for, got inspired with a couple of models from another site and decided to remix one of them, so, that's why I include the original shapes with my remix, I hope it works as well as I imagine.
