Like 'Your sun compass', this pavilion has no curtains closing it off from the surrounding desert. Instead, myriad bands stretch from the outer perimeter to a sculptural construction at the centre, forming a striped canopy that casts patterned shadows on the ground. The sculptural construction suspended at the centre is formed from two perpendicularly intersecting elliptical discs, each glazed with three tones of dichroic, colour-effect-filter glass. This material reflects certain wavelengths of light while allowing others to pass through it, so that the glass appears to be a different colour depending on the angle at which the light hits it and the position from which it is seen. Here, the colours of the shadows produced – cyan, magenta, and yellow – correspond to the primary colours of the subtractive colour model. When the shadows overlap, the colours mix to produce the secondary tones of red, green, and blue. When the sun reaches its highest point, the projection on the ground directly below aligns to form an ellipse divided equally into red and green, with red indicating south and green north. This work reflects Eliasson’s enduring interest in colour theory and light as the basis for aesthetic and spatial perception.
