World Pillow Fight Day is an initiative of the Urban Playground Movement, a group that organises fun public events all around the world. Their goal is to encourage people to leave their TVs and go out into their "urban living rooms" to connect with others. The wonderful thing about World Pillow Fight Day is that it takes place without the need for corporate sponsors, permit procedures or police interference. It's all about spreading pure freedom, creativity and happiness in the public space. Joey van Plateringen sent us these photos of the Amsterdam Edition of International Pillow Fight Day that was held on april 4.
