Eqgen is an experiment to create visuals from mathematical expressions. It consists of a customizable expression generator and simple canvas rendering. The generator takes a (user-defined) set of functions and operators and a set of constant values and variables and then randomly builds expressions for x, y coordinates and r, g, b color values. This system is then continuously evaluated to plot points on the canvas.

Eqgen even spawned that were shown at the Fantoche 2016 GIF programme.

Tools: JavaScript, HTML5 Canvas, math.js to parse expressions
