‘Lyshus’ simulates the sun for places in the world with the least hours of sunshine. This project simulates three features of the sun: The daily sunpath, the height difference during the seasons and at last our perspective to it’s position and size. This last feature is the most difficult to simulate because of it’s distance and dimensions. We perceive it as a small sphere which seem to remain on the same spot, wherever we move. This feature is simulated by an illusion of perspective.
