Via the always inspiring Colossal, check out this amazing art installation by Daily Tous les Jours in Montreal: a series of 21 huge swings along one of the city's boulevards, computerized to play musical tones when they're in motion. Each swing has its own distinct tone, but when all 21 swings are simultaneously in motion, then surprise! The whole set play in harmony. The point is to show how we can do so much more when we collaborate with others.
Check out the video about the project, below. Even the video is mesmerizing.
