This demonstration generates beautiful pictures by drawing lines between points on a circle.

Imagine a number of points *N* equally spaced on the circumference of a circle. The points are numbered from 0 to N-1. From each point *n* a line is drawn to a point on the circle corresponding with the product (or its remainder after divided by N) of *n * m*, where m is the multiplier.

Arrow up and down: decrease/increase number of points.

Arrow left and right: decrease/increase multiplier

r: restore
