Permanent art installation at Holmens Kanal 20 in the center of Copenhagen. It has been completely renovated by The Danish Building Agency in 2017-2019.

The functionalist building was drawn in 1937 by architect Fritz Schlegel and was originally the institution Overformynderiet, that worked as guardians of minors and women before emancipation in 1899. The 81 lamps (references the year 1899 : 18 - 99 = - 81) are made in brass, glass and solid oak; 100% reusable materials. They are programmed to follow the cycle of the seasons over the course of a year and play different light patterns according to eastern astrology and their symbolic material properties. The purple waves in the ceiling are painted with natural chalk paint like traditional houses and cut to in the same pattern as theta brain waves, that can occur during deep meditation, immense creativity or as a natural state of small children 40% of their awake time...! Red and blue symbolizes feminine and masculine qualities in the Korean symbol taeguk and mixed together they become purple. Also a prominent color in the 1960/70s psychedelic period. The HK20 building is the residence of the Danish Ministry of Employment and the Ministry of Climate and Energy.

From 2022 the completion of a second art installation will take place at the headquarters of the Ministry of Climate in the other part of the building.
