The body enters a totally darkened space filled with the sound of electricity. The sound of electricity represents in a symbolic way the invisible world of data transmission omnipresent in the surroundings in which we live, a transmission which to a great extent takes place via optical fibers, used for the fastest and most accurate transmission of digital signals. When the body enters the space, vibrations are created, the product of movement and speech, during which the optical fibers are activated, moving in different directions. The intensity and duration of the light and the movement of the fibers are determined by the intensity of vibrations from the foreign body in the room. Moving around the space, the body excites and carries out interaction with the luminescent fibers, and indirectly creates a spatial luminous drawing. With every body-sensor-fiber connection, a new spatial drawing is created, the duration and intensity are being determined by the body and its operations in the space. With every movement tracked by a sensor, the body keeps the drawing present. If the body ceases to be active, the drawing too will be passive − it disappears, turning into a dot. The process in which the drawing vanishes is visualized in the reduction of intensity in the fibers too, creating an impression that the drawing is receding into the distance, and in this way, vanishing in space.
