slide-in banner code

HI, I want someone to supply html code for a banner slider that does the same as the slider banner on the front page of [login to view URL] As you can see when u look at that site, it is a simple "slide-in" with a close button, looks like multiple banners can be loaded in it (perhaps rotated from a source file of banners). I cant tell for sure, seems to me to be DHTML - so again, I need code to do exactly the same on my site. Very urgent, need it immediately.
