Hopalong Orbits Visualizer: Stunning WebGL Experiment

Just discovered Barry Martin's Hopalong Orbits Visualizer -- an excellent abstract visualization, which is rendered in 3D using Hopalong Attractor algorithm, WebGL and Mrdoob's three.js project. https://www.youtube.com/watch?v=YjuexKGHLTM Hop to the source website using your desktop browser (with WebGl and Javascript support) and enjoy the magic. PS: Hopalong Attractor Algorithm Hopalong Attractor predicts the locus of points in 2D using this algorithm (x, y) -> (y - sign(x)*sqrt(abs(b*x - c)), a -x ) That is, $ x= y- \mathrm{sign}{(x)} \cdot \sqrt{…
