Desktop Delerium: Making Of / 900 Screenshots
One of the features up at BD4D right now is a Tcheupel Garanger's wonderful movie (enter, and click on "Making of / Screenshot) that'll make CAD or other desktop monkeys feel better about all the time they spend staring at a screen. I suppose you could do something vaguely similar with this, but there'd be no labor of love in it. (Makes one wonder exactly how many windows one opens and closes over the course of a day.)
