The significant architectural element in this gallery space is a circular window. This window is almost at ceiling height facing northwards. The idea was to create a second light spot that travels in the opposite direction towards the real sunlight. Both would meet and overlap on the floor at noon dis/reappearing at the same time. On a sunny day this procedure takes about 6-8 hours. The slides were taken at about two o'clock pm on a sunny day. The main aspect I tried to work out, was the inversion of a simple well-known and predictable thing: The trajectory of the daily sunlight.
