Informatica Interactive Seesaws on the Streets of Montreal Emit Light and Musical Harmonies 25 Aprile 2016 admin Currently on view at the Place Des Festivals in Montreal, Impulse is a new public art installation comprised of 30 completely illuminated seesaws and a series of video-projections on nearby building facades. When the seesaws are used they “activated” and begin to emit tones resulting in various musical harmonies. The project is part of a collaboration between CS Design and Toronto-based Lateral Office.
