Drawing & Undrawing #4

This animated drawing features a system of lines chasing invisible targets. Each line chooses a random behavior of pursuit. It can follow a target, orbit, spiral towards a mark, or scribble at the target location. Some lines draw their path; some lines erase anything they pass. In this way, the system creates white space and fills it, always trying to strike a balance of making and unmaking.

Built in vanilla Javascript on a 2d canvas.
