Eriksdalsbadet is Stockholm’s largest public bath with a section called the ”adventure bath”. Different patterns were created out of floor tiles in bright colours. Spotlights with a range of different coloured lights were mounted on pillars around the pool, making the colours stronger. On two pillars there are spotlights with red and green filters. These are programmed to change colour randomly. The red-green-yellow-black pattern changes in different coloured lights. In green light dark horizontal lines appear and in red light dark vertical lines appear.

From Order to Chaos. This was a further development of the floor pattern used at Södra Station. The pattern consists of five shapes, of which one is a square. The pattern can make both a symmetrically organised form and a form that never repeats itself.

Ceiling and a floor for The Swedish Pavillion at the World Exhibition in Seville. The theme was ’the inspiration of light’. The project explored the interaction between coloured light and surface colours. The ceiling was painted in a pattern that consisted of the physical basic colours red – green – blue as well as black and white. Circle bows of cyan and yellow cut the pattern. The circle bows have their centre point about 60 meters outside the building. The ceiling could be lit with a spotlight and dichromatic filters in red — green — blue with the same spectral curves as the painted colours.

With red light, all the green coloured become black. In green light, all the red surfaces become black, in blue light the yellow bow becomes like a black shadow etc. By changing the coloured lighting totally different patterns appeared.

I created 20 different images, programmed into a computer, that repeated in a six-minute sequence from nightfall until morning throughout the six months of the exhibition.

The building is now situated in Grythyttan and houses The Restaurant Academy.
