In 1965, the Italian artist and designer Bruno Munari presented the Tetracono with an event and an exhibition at the Danese showroom in Milan, inviting viewers to "meet the Tetracono" as if it were a person. However, Tetracono is a multiple object, a stern black steel cube measuring 15 cm that houses four aluminum cones, each painted half red and half green, designed with a mechanical movement at four speeds on an 18-minute cycle. Its function is to "show forms as they are in the process of transforming."
