Convergenze parallele is an audiovisual installation in which airborne dust particles passing through a beam of light are tracked, visualized, and sonified in realtime by a custom software system. The installation reacts to air movements in the exhibition space, allowing the viewer to see and hear the amplified movement of dust particles. “Convergenze parallele” explores the poetic potential of revealing and transforming the imperceptible. The custom software uses a video camera to capture the activity of dust articles passing through the beam of light. It then analyzes the video signal to track the location of individual dust particles, and reveals each particle’s trajectory in the image-processed projection. The physical particles draw traces of their otherwise invisible motion on the digital screen. At random intervals, the software artificially saturates the system by briefly activating the fan-a cloud of dust fills the beam of light and creates dense and stunning patterns of particle trajectories and sound.
