Has anyone been to amazon lately? I want to make a layer ad for my site the way amazon has that ad that drops down from the menu bar in the middle of the page.

The ad drops down for a couple seconds then scrolls back up and moves to the right side of the screen, where the user can click on it if he/she desires to see its contents again.

A lot of major sites are using these ads these days. TVguide.com uses them as well.

anyone have any idea where to get a script that make these?

thanks,
bobby
