title: CSS3 Transformation while scrolling
body: <p>Does anyone know of a good tutorial to achieve this? (as seen here: <a href="http://www.contrastrebellion.com/" rel="nofollow">http://www.contrastrebellion.com/</a>)
  I've looked at the code used on that site and finding it awkward to pull out what I need.</p>
  
  <p>Much appreciated,
  Thanks</p>
  
  <p>Edit: Also seen here: <a href="http://playgroundinc.com/" rel="nofollow">http://playgroundinc.com/</a></p>
  
  <p>What I want to achieve:</p>
  
  <p>To rotate a png as I scroll down and the speed of rotation to match the speed of scrolling.</p>
