In a related note, a Japanese video production group is being sued by Starbucks for unauthorized use of their sign in the background of their dance video.
oh shibuya....how many days i wandered down your streets to and from language class and shopping......i miss you......this video totally brings back memories...
check out improv everywhere at youtube - they do similar things... like big pranks. There's a food hall musical and synchronized mobile phone. Our school did the big time freeze. I think you can try some yourself!
Is everyone so fashionable in Shibuya?

Interesting how there's a variety of people in the dance group.
