procedural mesh generation

Generates an algorithmic 3D OBJ file with ThreeJS and Node.js.

# print to stdout
node generate-mesh.js > test.obj

# write to file
node generate-mesh.js test.obj

Playing with unsafe can be quite fun.

w/ speed up or slow down:
ffmpeg -i INPUT -crf 14 -vf "scale=640:640, setpts=1.0*PTS" -c:a copy -tune grain OUTPUT
(adjust crf for compression amount and 1.0*PTS for speed up / down)
w/out speed up:
ffmpeg -i INPUT -crf 14 -filter:v scale=640:640 -c:a copy -tune grain OUTPUT

A straight forward EventEmitter implemented in Javascript using ES6
let isFunction = function(obj) {
return typeof obj == 'function' || false;
};
class EventEmitter {
constructor() {
this.listeners = new Map();
}
addListener(label, callback) {
this.listeners.has(label) || this.listeners.set(label, []);
