Optik is a colourful and playful interactive sound and light installation that includes ten large gyroscope-like forms with dichroic film at the centre that each play a different music instrument while reflecting any ray of lights during the day, and refracting the inner rings lighting at dusk.

On March 3, Yonge-Dundas Square will celebrate Optik with opening night activities from 5pm-11pm including free warm beverages and treats, plus visitors will have the opportunity to be broadcast to five digital screens in the Square as the installation acts as a photo booth for one night only.
