Human LCD - Amazing

South Korea: Boys cheering for their soccer teams. The most amazing thing is that they do this with their CLOTHES (not holding up cards). they have a jacket that is one color on the back, one on the front, and that they can open or close to show a third color shirt on the inside. One school has also figured out how to use their pants to make shading.

Wow. I want to know what sort of system they use to coordinate all these different moves so perfectly. Looks stressful.
