Pretty neat.

If you leave the site open and run the following code snippet, you'll be able to heat your house with your laptop.

  window.onscroll = function(ev)
  {
    if ((window.innerHeight + window.scrollY) >= document.body.offsetHeight) {
      window.scrollTo(0,0);
    };
  };
  
  function pageScroll()
  {
   window.scrollBy(0,1);
   scrolldelay = setTimeout(pageScroll,10);
  }
