Epicycloid is a curve that is formed by tracing a fixed point on the circle that is rolling around outside a static circle. Animate this tracing steps with Python Turtle.
Moving objects can give 3-D depth effect called kinetic depth effect. Draw the following Stereokinetic Effect where rotating circles generates an interesting 3-D effect. Idea from https://michaelbach.de/ot/mot-ske/
Use the following parametric equations to draw a butterfly curve. In the equation above t is the parameter of the equations. Let it range from 0 to 12π gradually with
