WebGL playground

WebGL playground lets you type in your WebGL script and see the results on the same page. The editor lets you work on the JavaScript code and the GLSL vertex/fragment shaders (if you have any) at the same time in a convenient way. Everything is organized, formatted and includes syntax highlighting. You can use arbitrary JavaScript libraries to create your effects, combine multiple fragment and vertex shaders, handle user input, and more. Check it out here.
