Mystic Rose

The mystic rose is a pretty simple pattern, yet it looks cool. It works quite simply: you have a circle, the circle has 'N' points on it (they don't necessarily need to be evenly spaced), and then each point on the circle connects to every other point on the circle.

A simple demonstration for this is : http://demonstrations.wolfram.com/TheMysticRose/

One solution for this in p5 and Processing was this : https://gist.github.com/AlcaDesign/7ec612e94b19f9a2865a8f1cbcd95573 although there are a few performance issues.

Note : To debug certain issues (too many/too little lines being drawn - and other related problems) the formula (N² / 2) + (N / 2) calculates how many lines should be drawn with a set number of points. N represents the number of points on the circle.
