A pillow fight flash mob is about to happen in french speaking Switzerland (probably Geneva or Lausanne). From wikipedia:

A pillow fight flash mob is a fad that has emerged from the social phenomena of flash mobbing. The flash mob version of massive pillow fights is distinguished by the fact that nearly all of the promotion is Internet-based. These events occur around the world, some taking the name Pillow Fight Club after the London pillow fight group.
The trend owes much to uses of modern communications technologies, including decentralised personal networking, known as smartmobbing. Word of the events spreads primarily via digital means, usually on the internet via email, chat rooms and text messaging which result in seemingly spontaneous mass gatherings. Pillows are sometimes hidden and at the exact pre-arranged time or the sound of a whistle, the pillow fighters pull out their pillows and commence pillow fighting. The pillow fights can last from a few minutes to several hours.
