I've been debating for a while whether to post this one as a map-related animation. I figured I'd do it in this backlog catch-up session. You may have seen this or heard about it: The composer Eric Whitacre wrote some music and video'd himself conducting it then let it loose on the internet for anybody to record any of the choral parts of it that they wished to record themselves singing. Then they submitted the video/audio of their rendition and Mr. Whitacre edited it all together into this animation of over 1700 singers in about 60 countries. It's a fascinating experiment and the music is pretty... but is it a map-related animation? Enjoy it at any rate.
