[JS] Nice marquee/ticker-tape code

[Augmented]

I'm after a scrolling ticker-tape implementation in javascript, and due to time I just need to drop one straight in. Anyone know of a clean, unobtrusive cross-browser version of the dreaded <marquee>?
Only specific requirement is that the content of the scrolling text be relatively simple to edit.

Thanks .

<script language="JavaScript1.2">

//Specify the marquee's width (in pixels)

var marqueespeed=2
//configure background color:
var marqueebgcolor="#DEFDD9"
//Pause marquee onMousever (0=no. 1=yes)?

Thanks, though that's actually the one I've already got the code from (porting over from an old site) . Does the job fine, but was looking for something not relying so much on document.write. Might just stick with it and look into tidying it up at a later date if time permits.

Hehe.. it is a bulky one, but it's the cleanest I've found so far that doesn't have that horrible stutter.
