vertical autoscroll on mouseover - like deviantart.com "Project giveaway" has

http://www.deviantart.com/ is vertically scrolling the content of one of
their container upwards when you move your cursor over it. and on
mouseleave, it scrolling back down.
You can see it in action on their main page - right now at least - in a
container with the text "Project Giveaway: 100 point giveaway #4". I'm
wondring how they do this?
Found this line of code trough firebug:
onmouseout="if (window.LitBox) LitBox.out(this)" onmouseover="if
(window.LitBox) LitBox.hover(this, true)".
So I tried to google for "LitBox" - but didn't get any luck. All I found
was lightbox and listbox...
The exact effect is what I'm looking for.
Anyone know how?
