Design studios Lateral Office and CS Design collaborated with EGP Group’s engineers to produce 30 interactive seesaws that emit radiant light and sweet sounds. The entire installation, called Impulse, is located in Montreal’s Place des Festivals, where visitors can now embrace these playground toys to create their own art. Once they’re in motion, the seesaws generate harmonious tunes and illumination through their built-in speakers and LED lights. These pieces constantly change as they move up and down, allowing visitors to become spontaneous composers with one-of-a-kind instruments. The surrounding buildings are also incorporated into the installation experience, as imagery inspired by the seesaws is projected on them. (source).
