Animated cursor support in web applications?

You can make it happen with the help of a bit of javascript:

Add to your css

#container {
   cursor   : none;
}

#cursor {
  position  : absolute;
  z-index   : 10000;
  width     : 40px;
  height    : 40px;
  background: transparent url(../images/cursor.gif) 0 0 no-repeat;
}

Then add to your js

Straight Javascript Version

// Set the offset so the the mouse pointer matches your gif's pointer
var cursorOffset = {
   left : -30
 , top  : -20
}

document.getElementById('container').addEventListener("mousemove", function (e) {
  var $cursor = document.getElementById('cursor')

  $cursor.style.left = (e.pageX - cursorOffset.left) + 'px';
  $cursor.style.top = (e.pageY - cursorOffset.top) + 'px';

}, false);

Jquery Version

$('#container').on("mousemove", function (e) {
  $('#cursor').offset({ 
     left: (e.pageX - cursorOffset.left)
   , top : (e.pageY - cursorOffset.top)
  })

});
