// If you have a RequestAnimFrame loop you can use noise.generate() to create a new pattern. 
MainLoop() {
  image.generate();
  requestAnimFrame(MainLoop);
}

// Or apply it as a style to your webpage background
document.body.style.backgroundImage = "url(" + image.domElement.toDataURL("image/png") + ")";

...etc
