the nearer the person comes, the more the knocks are intensified and accelerated, until when the person is right in front the machinery is running at high speed, thus weaving a dense carpet of rhythms. the window itself, but also the parts knocking on it, are slightly manipulated to cause a wide variety of different, interweaving sounds in a small space. through subtle inaccuracies and constant slight variations of the robots, the installation appears to become organic and alive.
