Pop up stores are all the rage now, but Adidas took it a step further with theirs. At the 2011 Primavera music festival in Barcelona, Spain, the company created an installation that looked like a giant Adidas shoe box!

Not only the box was cool, but once inside you could take a 180 degrees picture of yourself jumping and get a gif. Like in the matrix, but cheaper ;)

I am a neatoramanaut but never expected one of my projects appearing in neatorama. Yay!
