Page Transition Effect - IE

An example: 
(You can save the text below as a html page and try opening it from another page to see the transition):

<html>
  <head>
    <meta http-equiv="Page-Enter" 
      content="revealTrans(Duration=1.0,Transition=2)">
    <meta http-equiv="Page-Exit" 
      content="progid:DXImageTransform.Microsoft.Pixelate(duration=3)">
    <title>Sample</title>
  </head>
  <body>Sample</body>
</html>

Additional DirectX Transitions
Note: Some of these filters will only work on IE 5.5 or later.  These transitions are not very commonly used, probably because not many know about them - which means they might be dropped in the future by Microsoft?  Hope not.  The Pixelate and Gradient Wipe are cool.
