Collaboration exercises

I've chosen two collaboration exercises:

1.

This is "an exercise in musical cooperation. Cooperation emerges when the behavior of each individual depends on the decisions of the rest of the group: it´s a game where, from the start, you need to adjust to the actions of others."
21 Balançoires (21 Swings) "is a giant collective instrument that stimulates ownership of the new space, bringing together people of all ages and backgrounds, and creating a place for playing and hanging out in the middle of the city center." (Daily tous les jours and Luc-Alain Giraldeau).

2.

Reverse Times Square: "Over 2.000 people move backwards through Times Square, making it look like time is going in reverse to unsuspecting tourists and New Yorkers. Participants met in Bryant Park to receive instructions and synchronize their watches before heading over to Times Square and blending in with the crowd. At exactly 3:15 PM, participants bagan moving backwards for exactly five minutes." (Improv everywhere)

We can put it this way: children are creative each and every single day, enjoy being surprised, puzzled, everything is a game to play, it's how they learn.
We can practice collaboration: in amusing and meaningful group exercises (1.) and in new opportunities to enjoy being surprised and change our perspective (2.).
