So this is apparently from a synchronized marching competition at Nippon Sports Science University in Japan. If you get a lot of people together to do hard things at the same time, it's pretty impressive. If you get a huge amount of people to do the simplest thing in the world, you've got to be creative for it to be worthwhile. A lot of really impressive stuff goes down in here, but those crosses at 1:50 really blew me away.
If you like this Japanese brand of insane synchronization but want more acrobatics, then I have to point you in the direction of Men's Rhythmic Gymnastics. I've only seen teams like this from Japanese universities but I'd really like to see this kind of thing done on a global scale (I'm looking at you, Russia.)
