Les Boules Roses installation in Montreal. The piece features 200,000 resin balls in three sizes and five tones of pink. Using bracing wire, the rows of balls are laced through the trees in nine different suspension patterns and at varying heights. The final product is a magical canopy stretching over 1km between St. Hubert and Papineau streets. You can see this gorgeous temporary rooftop from now until September 16th.
