prolly more like so many seconds/minutes/hours or on refresh. im adding cybs rotating banner which you can place in as many places as you want, but it shows the same ads in same order in all those places. i thought something like yours with lots of different, smaller rotating banners would be real cool. that way say each of the 21 ad spaces you have on yours, you can have like 4 or 5 that rotate in each spot. this will give you 100 or so different adds all with their own links, but only take up the space of 21 on your page.
