# Copie de Multiplication Wheel:

Multiplication wheel: Equally spaced points around a circle correspond to a number (you can change this number with the first slider). Lines are drawn in to connect each number with one which is a certain amount bigger (the second slider). By varying this, we can see how the pattern evolves with time. Look out for cardioids and nephroids, etc.
