The tetrahedron occupies the surrounding “artificially” shaped slag heap landscape like a surreal sign. While it is a geometrical copy of a pyramid, it is a filigree and transparent structure rather than a solid one.
At night, the “slag heap happening” becomes a “light happening”. Düsseldorf artist Jürgen LIT Fischer transformed the top of the tetrahedron pyramid into a bold “light sign” made of yellow and green lines of light.
The “light sign” above the slag heap thus shows the tetrahedron to be a place where views in a wide variety of directions reflect the diversity of the surrounding colliery landscape and yet enable visitors to experience the panorama as a unified whole.
