These site specific installations consist of special tubes, filled with warm light (led). The installation forms an arrangement of parts or elements of circle-like shapes of light, loops or spheres which are juxtaposed. Viewed from different angles in the space, the installation generates distinctive perspectives, distortions, reversals and light drawings. It sometimes divides or cuts through the space itself. This way the installation draws attention to acts of composing, constructing, and framing. And sometimes dividing or cutting the space itself. The light constellations can vary in size and lengths and are site specific for large venues or buildings such as the Byzantium, the first residential building by Rem Koolhaas. Other constellations were made for more intimate spaces such as galleries, corridors and chambers.
