This illuminated ceiling is constructed in three sections which are technically and aesthetically very different but form one unique attraction.
The main area is a grid with acrylic glass panels which bear a light blue filter on the upper side to imitate real sky. The ovoid shaped section consists of stretched foil illuminated with fluorescent tubes. In the center of the scrim a huge metal cylinder is pending from above, adjusted so that the edge just touches the scrim on the top. Inside the cylinder RGB-fluorescent tubes allow colour changes reminding of the pupil in an eye.
