demotool is a minimalistic tool for making WebGL intros. It aims to have as little javascript as possible, while providing you with a WebGL context to draw your shaders on. It also provides a minimal tracker for creating music.

- Use a javascript minifier before using
pnginator.rb. It can significantly reduce the size of the end product. Many minifiers don't like the backticks though - you might need to pass the shaders as strings instead - sadly, that means you cannot have newlines, but you need to have each shader on one line. - Use a shader minifier for the shaders before passing them as strings in the javascript. Again, significant reductions.
pnginator.rb is included in this repository, as it is helpful for building the final tiny "executable". I don't claim ownership to it though: I modified it from a gist written by Gasman, based on an original idea by Daeken
