Is it supposed to be funny? I think it's a neat thing visually, the same way time lapse footage is. It's not particularly useful just something cool to watch. The switch from a single person to the whole crowd is a shock. That's the draw.
Though they said they'd never do it (the idea was tossed around that a harlem shake could be done for the community RTX video) I still hold out hope that maybe it will come out of an RT life or something.
