webgl crt shader

A free GLSL shader demo — play it in your browser, no install. Tweakable CRT shader for web canvas, three.js, etc. If you use this in your game/app/website I'd love to hear about it. Let's call this Serenity Shader if we need a name to refer to it as. This is a WebGL shader, written in GLSL, intended for use in web browsers.
