$Coding Challenge 185: Unfolding Fractals 25% off The Nature of Code book with code CHOOCHOO at https://natureofcode.com (comes with exclusive sticker+bookmark). The Dragon Curve fractal is created by repeatedly folding a strip of paper in half, then unfolding it to form a curve. In this challenge, I attempt to code an animation of the Dragon Curve forming with p5.js in JavaScript.
