Icon attached to mouse:
To use this, code, copy the script from this page's source, and insert the following layer at the bottom of your code:

<div id="icon" style="position:absolute; top:10px; left:-50px;">
  <img src="icon.gif">
</div>

Replace the image with your own image, or any HTML element

To change the x and y offset of the icon, go to the start of the script and edit the following lines (should be self-explanitory):

var iconxoffset = 10;
var iconyoffset = 10;

This script works in both IE and Netscape.
