For this year’s Amsterdam light festival, artist and designer, Hagar Elazari, created a collaborative art project where spectators are encouraged the to participate and intervene in her artwork. The light installation is designed as a large toy, in which people move around the triangles on top of a long illuminated surface to create new patterns. The patterns are achieved by changing the hues and transparency levels, the more layers added the darker the hue becomes and vice versa.
