How do you do that neat flyout that you have added to your site.

It is a div positioned with css and animated with jquery.

some css like:

div.flyout {
  position: fixed;
  background: #f00; /* place some image or so */
  width: 500px;
  height: 500px;
  right: -480px; /* place outside screen, only 20px visible */
  top: 50%;
  margin-top: -250px;
}

then some javascript:

$('div.flyout').hover(function(e){
  $(this).animate('right', 0);
}, function(e){
  $(this).animate('right', -480);
});

That would be the basics, you should have of course a div with a class flyout on the page, you can add more to the flyout like a banner or so, also you can play with the css and animation.
