Light Therapy in the Quartier des spectacles 2015

Design Competition - Participatory Installation and Video Projections

Bascule jour

Lateral Office, CS Design Inc, Iregular, Maotik, Mitchell Akiyama and EGP Group


Impulse is an interactive work comprising seesaws of various sizes, with lighting and sound. To activate them, one person sits down on each end. The seesaws, fitted with LED lights and speakers, then produce a series of beautiful sounds. The intensity of the light varies as the board’s angle changes.

The installation and its streamlined design will delight children and adults as they play with the sounds and lighting effects it produces, filling the Place des Festivals with a dance of sounds and lights, bringing joy and warmth to the winter’s cold, short days and dark nights.

With their motion and hypnotic rhythms, the architectural video projections will echo the seesaws in the Place des Festivals. Playing with the ideas of balance and unbalance, symmetry and asymmetry, tension and harmony, the projections, accompanied by original soundtracks, will enhance the primary work.
