title: HyperSpace from codepen doesn't work for me when I copy it
body: <p><a href="http://codepen.io/noahblon/pen/GKflw" rel="nofollow">HyperSpace</a> is neat demo that (I think) only uses css.
  But when I copy the html and css to my directory, <a href="http://www.phillipsenn.com/LR/WinnerWinnerChickenDinner/HyperSpace/HyperSpace.htm" rel="nofollow">it doesn't work</a>.</p>
  
  <p>Q: What am I missing?</p>
