How to capture WebGL/Canvas by piping data over a websocket.

This Gist builds on https://gist.github.com/unconed/4370822 from @unconed.

Instead of the original method which writes to the browsers sandboxed filesystem here we use a websocket connection provided by websocketd to pipe image data to a short python script that writes out the .png files to disk.

	var git = require('nodegit');
	git.repo().init("foo", true, function() {
	git.repo("foo", function(err, repo) {
	repo.branch("master", function(err, branch) {
	console.log({
	err: err,
	branch: branch
	});
	console.log("doing something else");
	});

	#!/bin/bash -e

	URL=http://chaosbay.hq.c3d2.de

	if [ -z "$1" ]; then
	echo "Usage: $0 <file/dir>"
	exit 2
	fi

	if [ -x "$(which mktorrent)" ]; then
