Javascript: Any light text div fader scripts?

Hi all,

I wondered if anyone can point me to a text fader script that will allow me to fade in around 5 different < div > elements in rotation.

Ideally it has to be light, so no fancy moo or prototype scripts.

Somebody did email me this but didn’t tell me how it would be implemented: http://snipplr.com/view/3512/script/
Anyone make sense of this link? How would this work with some text?

Many thanks
