I'm saving this one, too. Very good mood-synch. Some of the clips are, umm... odd; that very last one, for example. I don't get it, but if it works for you, then it's good.
I was thinking that those keys and rectangles could have had more of a "floating" look with drop shadows. Real easy to do with Vegas (ref. track motion settings).
While I didn't have a problem with the rectangles, the transitions I'm not so sure about. Using an odd transition or effect only once can be risky. It indicates lack of commitment or perhaps pandering to the audience. That one with the rectangles (was that the Sony portal transition?) looked especially out of place.
Nice job.
