In Memoriam Adriano Olivetti (1962) by George Maciunas is based on used tapes from an Olivetti adding machine. Adriano Olivetti was an Italian engineer and entrepreneur known worldwide for manufacturing Olivetti typewriters, calculators, and computers. The score by Maciunas assigns every performer with paper strips from the calculator in their hands, and each time an assigned number on the paper comes up, the performer executes a specific action allocated to the number, such as: to fold and unfold an umbrella, to blow a whistle, to jump up and down, to make a deep bow, to give a salute, to outstretch a finger at someone or something. The performers in Festum Fluxorum Fluxus: Musik und Antimusik – Das Instrumentale Theater held at Staatliche Kunstakademie, Dusseldorf in 1963, were Bengt af Klintberg, Frank Trowbridge, Tomas Schmit, Wolf Vostell, Arthur Køpcke, Daniel Spoerri, and Emmett Williams. The second from the left of the picture is Nam June Paik wearing a round cap.
