Before clocks were introduced as such, people used celestial bodies, constants for orientation to make time tangible. People played a secondary role in that system and had to arrange with the continuum of time. In our age the development of ever more new forms of dividing time goes hand in hand with the fear of what it ultimately its representation. The foundation for the “Tide” installation is the aquarium as microcosm that is regulated by human hands, and the engagement with water as “projection space.” On various levels there is an interaction between light and water, yet the mechanisms remain mysterious and separated from the associated natural event. Through rhythm, the playful imitation aims to lead to a meditative appreciation on the audio and visual level in which the perception of time is above set rules.
