ꉻ is set to the natural light rhythm in The Hague. The distance between the center and the elliptical structure is the same ratio as the sun from the orbit of the earth. The light, emitted by a green laser and reflected by the structure, resembles aurora borealis, a light that can only be observed at night on the earth poles. This phenomenon is a consequence of solar wind: small, highly charged particles from the surface of the sun, that then collide with oxygen in the atmosphere. The effect can be seen at best around solstice, the longest night of the year, the night of December 26th. ꉻ moves along the furthest point in the orbit: the darkest time in the year, when the light is best visible.
