One aspect that particularly interests me in audiovisual installations is the tactile interactive aspect, with the possibility of influencing the sound track or the visual aspect. A child standing in front of one of my installations should instinctively be able to activate its actions, either by shaking whatever is within reach, by turning the knobs on the machines, or by waving their hand. This inter- activity is also reflected in the concept of feedback, which consists of looping the output of a system to its own input. This technique enables a kind of parallelization of several processes that feed off each other. I’m thinking particularly of the double installation Mycorrhiza, where the feedback, although digital and algorithmic, results in unpredictable, even chaotic, and therefore organic effects. The person interacting with these installations is part of the system as a chaotic process in its own right, which causes the algorithms to act, but whose actions are also influenced by the results.
