The art of not speaking

A workshop. Probably 2006. 
What if you ran a communications workshop for members of the public, but didn't speak?
Not from the first moment of welcoming people, introducing the workshop, indicating it was time for an interval, thanking everyone for coming and sending them on their way?

For two and a half hours, no one spoke. But they danced. They hugged. They saw each other. They gave each other money. They played. They had visions of their future. They danced. They saw the potential for conflict resolution in getting people to meet and to not talk. A lot happened in a short space of time - without words getting in the way. 

No photos. Imagine everyone stacking the furniture in a (pretty tall) room and someone climbing to the top so they could hang from the ceiling while everyone applauded.
