In the masterclass, participants will assemble an agamograph - an optical picture that changes when viewed from different angles. A simple technique turns paper into a small visual trick. The masterclass is dedicated to an optical illusion that can be achieved independently. The essence of the work is simple and thus particularly captivating: on one surface, two or more images are combined, and the image changes depending on the angle from which it is viewed. It results in a small visual trick that immediately shows how perception is influenced by the angle of view. Participants will work with shape, color, and rhythm. The organizers provide all materials. For other events in St. Petersburg, look for KUDAGO.
