I recommend reading all of Dan Pink's Drive: The Surprising Truth About What Motivates Us, but this 10-minute video is a condensed and effective way to get the elevator version (tall building edition).
In addition to liking the ideas in Drive, I liked this video. Ever since my long-ago days as a draftsman and technical illustrator, I've felt there's something about outline illustration that enhances clarity. Simply animating the process of drawing it makes it visually compelling without getting in the way of the ideas.
Pink's Drive 18:40 talk at TED is also worth watching.
