I’ve made my own conversion to PDE Java 7 syntax from the original Python Mode sketch below: 🐍

Not only it runs on Processing 3 but also on browsers via [Processing.js](https://gotoloop.github.io/processing-js.github.io/reference/) (Pjs) + [Toxiclibs.js](http://haptic-data.com/toxiclibsjs) libraries. 🥳

There are some added small features like left-click pause/resume, right-click restart, middle-click toggle rendering, number keys for changing background color and key S for a snapshot! 🎨

Click the button “View App” at the right bottom side in order to run the sketch: 🏃‍♂️
