In 1976 George Cup & Steve Elliott presented the installation "30 screen projection # 12" at the Sidney Janis Gallery in New York for the first time. The installation displays a chorographie of 30 DIA-projetcors screening light without slides on a black wooden board. This installation can be seen as the link between the static oil paintings of the late 1950´s and the animation films of the late 1970´s. To work with light in motion was the base of many experiments of George Cup & Steve Elliott.
