From http://haptic-data.com/toxiclibsjs/:
“Toxiclibs.js is an open-source computational design library ported to javascript by Kyle Phillips originally written by Karsten Schmidt for Java and Processing. Examples of the original library can be found at http://toxiclibs.org
Toxiclibs.js has no external dependencies and can be used by itself or with any other library. Toxiclibs.js works great with the Processing.js visualization library for canvas, as well as Three.js, Raphael.js for SVG, or even just DOM manipulation.”
