I wonder if this can be done...
When we use Stumble Upon (yes, it is a wastage of time for most of the time until serendipity strikes!) we need to go click, click, click on that tab...but wouldn't it be great if the same thing were to be automated and the "Stumbled Upon" sites could be shown as a slide show at a user defined speed and suddenly when one of the sites catches our fancy we could stop the slide show and check it out only to resume the slide show later...Possibly we could even mention the number of sites to be randomly generated this way...it would be fun!
