I wouldn't normally point to someone else's advertising but go take a look at http://www.redbeemedia.com/ then click on the "The Big Picture" then "The Virgin Media Story", sit back and watch. (It's flash so I can't link directly, or rather, I can't figure out how to link directly).
It's a very clever Hitchhiker's Guide pastiche ... and an advert ... and a beautifully charming and simple technical business pitch that includes the line "as it has been clinically proven that intense study of process maps makes the human brain explode".
It really is well done. Trust me on this.
