can you say LOGOS?

please take six minutes and 24 seconds of your day to watch the most excellent visualization of data i have seen in quite some time. i wish i had made this. the voice-over is clear and calm, the visuals are equally clear and effective, visual scale is accurate and consistent throughout (no distortions to mislead viewers), motion is used very effectively to show changes in data, and sources are cited at the end. great stuff.
