Just click the green flag and watch! It's basically lots of points spaced around the circumference of the circle, and it draws lines between the number it is up to (0, 1, 2, 3, ...) and that number multiplied by the value of n. In the end it makes some really cool patterns! You can even find some in real life, for instance in the way light bounces around in a cup, so some of these can be visible on the surface of your coffee! Try 2 or 3 for the value of n to see these! My personal favourite is maybe 76, it creates a really beautiful pattern! Also, one of my friends suggested I put in 1.1, and I learnt the beauty of decimals!
