Ornella Fieres recorded her video work Tide (2014) in the Griffith Observatory in Los Angeles. In fast motion, it shows the simulation of the lunar phases as a projection on a ball. Further, the artist converted the data of her video into a sound track. Two versions of the film come about, one visual and one auditive, which are played back simultaneously. The video signals that have been converted into sound by the artist resemble NASA's audio recordings from space.
