Of all the string installations that have appeared on the site, this is the first one that moves. Artist David Letellier‘s installation Caten is housed in the Saint Sauveur chapel in Caen, France. The strings-hanging-on-strings are controlled by four motors and the entire assembly moves slowly to the resonate sounds of an abstracted hymn. David studied architecture, and in his own words: “the curves of the wires, created by the gravitational force, reflect the shapes of the church arches.”
