I just had an idea for an internal promotional tool, but I'm not sure if it already exists in some way, or if someone can write the script or knows someone who can.

Was just thinking that something like in the old Pop Up Videos might be kinda cool -- at a random time on certain pages, a little DHTML or Flash-type of alert could appear, then vanish after a short length of time. It wouldn't need to be huge and obnoxious, just a small blurb that pops up, delivers info, and goes away, all from an inconspicuous (yet visible) edge of the page. It could be used to advertise current news or specials, or mention upcoming additions or updates to the site.....lots of other things.....
