This project has been made from used windscreen wipers placed on the floor. They sweep the floor with a phosphorescent powder. This work constitute a research on dust moves on the floor. This installation question the main thread of a communication between 8 windscreen wipers creating a loop. Like a traffic, each wiper brings some of the phosphorescent dust. Dust represent the end of life and the events making a story. Phosphorus is also a question about technical industry, so efficient that we are able to imitate nature(light of the sun or growth for example). The installation goes from dark with phosphorescent light to UV light. After 10 minutes, a light in the center of the room is turned on to reveal the installation and recharge phosphorus in light.
