title: video as site background? HTML 5
body: <p>I want to use a video as a background instead of an image that automatically stretches to the whole screen (background).</p>
  
  <p>I would also like to rotate videos and images.. so that there is a random video/image displayed in any order.</p>
  
  <p>It would also be nice to know how to delay video playback, so that the video only plays once 30 seconds after the site loaded.</p>
  
  <p>thx!</p>
