Ferdinand Kriwet (1942-2018) installed four untitled neon works in the dining hall of the Ruhr University Bochum in 1971. His circular light sculptures of coloured Plexiglas, each about 2 meters in diameter, are a permanent part of the university building begun in 1964. Colour photograms of the four works of art were taken in a mobile darkroom that encloses them precisely. On photographic paper attached directly to the objects, a colour-inverted mirror image of the light radiating from them is created.
