Special thanks to Jaap Scherphuis who originally put CPM online making it widely available. Thanks to Bob Hearn for his super code, producing the first circle puzzle fractals and for his numerous talks clarifying Rc (critical radius) and how these fractals are produced. Thanks to Jason Smith for his Gizmo Gears Deluxe Render showing fractal movies and his fractal research. Thanks to Brandon Enright for his fractal code and his extensive mathematical analysis of Rc. Thanks to Andreas Nortmann for putting the Gizmo Gears jumbling question on the forum after Battle Gears failed and I suggested Gizmo Gears might be worth a try. Thanks to Oskar van Deventer’s energetic input and puzzle innovations and alerting me.
