Flash Mobile

Flash mob of the pillow battle held in Madrid.

Flash mobs are instant agglomerations of people in a public place to perform a certain action before an unusual combination, these dispersing as soon as gathered. The term usually applies to meetings organized via e-mail or media.
From Wikipedia.

Flash mobs are the actions of people together that make workers "break" with the routine and have fun, so as to not disrupt the plans of pedestrians.
I love this flash mob: http://www.youtube.com/watch?v=VQ3d3KigPQM
The people at a Liverpool Station danced to create this special T-Mobile Advert. Life's for sharing.
