Basically, I have requests for an Internet radio station loaded into a DJ site via AJAX - every 10 seconds, it checks for requests. If there's nothing new, obviously the <div> doesn't change, but if there is, then the <div> changes with the new data. How can I make the title bar flash (similar to that of new IMs in Gmail or Meebo) or something to notify the DJ that there's new content on that webpage (but only when there IS new content?)

Thanks!
