Simple Text Animation

Simple Text Animation

I have a simple script that displays some random text from an external .js array.

<script language="JavaScript">
        <!--
document.write(r_text[i]);
//-->
        </script>

This array has a simple random function at the end: var i = Math.floor(25*Math.random())

I want to display these strings without having to refresh, vertically scrolling from one to the next.

Can anyone tell me how to accomplish this using jQuery?
