From Brazilian multimedia artist Jarbas Agnelli, this is Cars on the Lanes, an experiment to find and translate the music in patterns around us. Agnelli writes:

Since everything moves (from galaxies to atoms) and every moving pattern can be read as numbers or notes, then everything contains music. When we cross this with the human spirit, and combine those patterns in a pleasant way, we have the chance to transform them in art. That’s the idea behind this project. On this first test, I used cars on a New York freeway, and choose small loops from several minutes of footage, picking special moments when the elements can be read as interesting musical phrases… The arrangement will come from the patterns themselves.
