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.
