Grabbing each frame of an HTML5 Canvas

Using PhantomJS.

Example with this canvas.

var webPage = require('webpage');
var fs = require('fs');
var page = webPage.create();

var NB_FRAME = 100;
var current = 0;

page.open('http://www.effectgames.com/demos/canvascycle/?sound=0',
function(status) {
  if (status === "success") {
      var current = 0;
      var grabber = setInterval(function () {
          var frame = page.evaluate(function() {
           return document.getElementById('mycanvas').toDataURL("image/png").split(",")[1];
          });
          fs.write("./frame-" + current + ".png",atob(frame), 'wb');
      if (++current === NB_FRAME) {
         window.clearInterval(grabber);
         phantom.exit(0);
      }
    }, 1000);
  }
});

or use ccapture.js.
