The municipality of Houten, near Utrecht in Holland, commissioned Lucien den Arend to make a sculpture for a raised mound in the central park which bisects Houten. Den Arend made a construction consisting of large and identical steel arcs, each having a chord of twelve meters. These virtually perform a rhythmic dance up and over the small hill. The total height above ground level is about twenty meters. He called the sculpture c.y.f.
