In the late 1960s, at the invitation of Umberto Eco, Eugenio Carmi began to collaborate with Servizio Programmi Sperimentali in Rai. After some research on perception, the artist proposed an actual “transgression” for the use of television medium: using cameras not to film the reality, but to create a completely abstract color video work. From an exchange with Rai technicians, the idea was born to use in an artistic way the disturbance generated when you point a video camera at its own playback video monitor. Thus began the first Italian videoart experiments of so-called “feedback” process, to get between 1972 and 1974 to the documentary Arte elettronica, arte della luce and the video work C’era una volta un re, and then, in 1977, the animated fairy tale Olivo verde vivo created by the painter’s daughters Antonia and Francesca Carmi with Giulio Masoni.
