I did everything in this tutorial: http://www.gcmingati.net/wordpress/wp-content/lab/jquery/newsticker/jq-liscroll/scrollanimate.html
It should be pretty simple.
<script type="text/javascript" src="http://code.jquery.com/jquery-1.4.2.min.js"></script>
<script language="text/javascript" src="http://www.gcmingati.net/wordpress/wp-content/lab/jquery/newsticker/jq-liscroll/jquery.li-scroller.1.0.js"></script>
<link href="http://www.gcmingati.net/wordpress/wp-content/lab/jquery/newsticker/jq-liscroll/li-scroller.css" rel="stylesheet" type="text/css"/>
<script type="text/javascript">
$(function(){
$("#ticker01").liScroll();
});
</script>
<ul id="ticker01" class="newsticker">
<li>
abc
</li>
<li>
xyz
</li>
</ul>
