** Use Turbo Mode ** (<Shift> key + Green Flag). - Keys <2>, <3> for other patterns. - Key <1> for the original pattern. - Pressing Key <3> while pattern of Key <1> is still drawing produces an interesting effect.
Hamid Naderi Yeganeh is an Iranian mathematician who uses complex trigonometric formulae to generate intricate art including fractals, tessellations, and animations. The technique that Yeganeh uses is to trace around a shape (such as an ellipse) but instead of drawing each point, it draws a transparent circle at each point. Thanks to @selim_tezel for Cycloids with Yeganeh Technique (Randomized) https://scratch.mit.edu/projects/226072919 I first learned about the Yeganeh Technique from that project. Thanks also to @kc021
