Simple little plugin that adds a trailing cursor effect to your mouse pointer. Add a fun touch to your site or just during festive seasons!
With this plugin, you can choose:
<ul>
<li>The trailing image to show which follows your cursor (default is a mouse arrow).</li>
<li>Adjust the fade speed of the trail and the rate of display.</li>
<li>Choose when to start/stop showing the mouse trail (such as only during a holiday season).</li>
</ul>
