Process Mapping

Your conference in Palo Alto definitely raised the bar for my own visual representations of information. Quite a bit of my work involves traditional process mapping of business activities (usually multiple department or divisions), and I was wondering if you knew of any good examples of process map layout or design. I’d like to get away from the “10 Visio boxes” on a page that I so often see, in order to present a true map of complex interdependent processes.
