Cool news ticker! Seems familiar...
Taking inspiration from the BBC News website ticker, jQuery News Ticker brings a
lightweight and easy to use news ticker to jQuery.
If you need a functionality like a Ticker, maybe Left to Right or Top to Bottom,
you could simple use the html marquee tag. Use javascript or jquery to update
it's content dynamically as you feed comfortable.
You can also alter it's motion behavior with onmouseover and onmouseout events,
like
<marquee behavior="scroll"
direction="right"
onmouseover="this.stop();"
onmouseout="this.start();">
Hover to stop!
</marquee>
Though the <marquee>-element, as suggested by mtk, will work in most browsers,
it is not standard HTML and should not be used, if standards-compliance is an
issue. You should then use the appropriate CSS-styles!
You can then put your content in almost any HTML-element and just "marquee" it
around as you like.
