The microprocessors are connected to infrared sensors, capturing the surrounding infrastructural flows, defining the frequency and amplitude of the rotation. According to this set up, each impulse is transmitted from one panel to the other, describing visual waves running from one side of the installation to the other, and then bouncing back while progressively loosing oscillation. All these principles relate the ‘micro-events' happening in the area to a unified play of light, colours and sounds directly derived from the rhythm of the city flows.
