"The fifth element" is a Metal and Light sculpture. The Metal sculpture is 2 by 2.5 meters. And the Light sculpture covers 300 m² in 6 meters high. It is Permanently Exhibited at Östergötland's museum, Linköping.

The sculpture consists of two parts with their separate and collective functionalities. The design consists of a metal sculpture made of mirror-polished metal sheets and a light sculpture that creates shadows out of the metal sculpture.

The light sculpture results from a complex light designing process in relation to the size and shape of the statue against the museum wall which acts as projection curtain. The sculpture is acting as a shadow-making filter too.

During the day, we see the full performance of a shiny metal sculpture, which reflects the fixed and moving objects and glow under the natural light. And at night, the manipulated shadows covers the main wall of the museum, the pool, the grass lawn, the sculpture platform itself and the side of the main entrance.

The shape of the sculpture is inspired by Plato's fifth element, the dodecahedron and presents ether, heaven, or the cosmos. A dodecahedron with twelve faces that are regular pentagons. The Golden Ratio governs the shape of a pentagon. For Pythagoreans, it symbolizes the generation of the cosmos, spirit or ether.
