Updated to use Three.js (r70).
Added a method for exporting canvas data as a PNG in a new window. Hit the "p" key while window focused.
Simple Three.js bootstrap based of their example code. Contains all the HTML, JS and CSS to run a basic example including WebGL detection (see below).
WebGLDetect.js detects if WebGL is useable (available and not disabled) then uses LazyLoad.js to load the large Three.js library and project code.
