Turbo mode needed (shift+green flag) unless you want to see process. A hybrid of three wheel cycloids and Yeganeh technique.
Learned about multi-wheel cycloids from a wonderful mathematics article I read many years ago, unfortunately, whose author I cannot recall. Thanks to great Scratcher SBissay for teaching me about pen opacity. Inspiration by the great Iranian computational artist Hamid Naderi Yeganeh's work: 10,000 circles https://mathematics.culturalspot.org/browse
