Every spring, an interactive installation takes over a high-traffic area in Montréal's Quartier des spectacles and sets a collective ritual. The installation offers a fresh look at the idea of cooperation, the notion that we can achieve more together than separately.

The result is a giant instrument made of 21 musical swings; each swing in motion triggers different notes, all the swings together compose a piece, but some sounds only emerge from cooperation.

This is truly lovely. I would like to see this someday, and getting back to Montreal is already on my life list. I think I would definitely want to try to get there while this is up some spring.
