Two light prisms by Heinz Mack

The two stelae with a triangular floor plan are made of colored, specially vaporized glass, which changes its appearance in many different ways with the changing light conditions and also with the position of the viewer. The stelae document a new, different reality at a central location in Vaduz. "They are the dreams that one dreams when light sleeps with matter." (Quote from Heinz Mack)
