A succession of vertical planes separate an inner space from surrounding corridors. The structure demonstrates an open system of primary and secondary elements, where the latter may be varied with regard to form and position without disturbing the expression of order. On both sides of the filled-in planes, strips of light filter into the corridor, forming a pattern on the walls. The scantily dimensioned openings make it possible to catch a glimpse of the objects inside. In a space-time context the sequence is a crescendo from the first view of the shadow on the screen to the full sight of all the objects.
