Over the years, sperimental communication and digital art exchanges have also been explored within the Plexus art journey.
1987, within the Art Co-Opera “Serpente di Pietra" in Gavoi, Sardinia, digital exchanges occurred via the Bitnet network between the Dax Group of Carnegie Mellon University and the Physics Department of the University of Cagliari, before the advent of the internet
1988, within the Art-Opera "Il Viaggio del Serpente", at the New York University Bobst Library, New York, experimental art interactions via fax, computer and telephone were explored with the University of Cagliari Dept. of Physics and the Dax Digital Arts Exchanges Group of Carnegie Mellon University in Pittsburgh
George Chaikin dematerialized via scanner an African canoe and tried to transfer its data via online to prof. Franco Meloni at the Dept of Physics of the University of Cagliari, with no success. Therefore, George gave to Sandro Dernini two big computer disks containing the dematerialized canoe data.
Within an art performance by Willem Brugman, Stephen Di Lauro, Isabel, Tania Gherstel, David Boyle, and Antonio Caboni, Sandro Dernini delivered to prof. Franco Meloni and prof. Francesco Aymeric at the Dept of Physics in Cagliari to check if it was possible to re-materialize the African canoe. The art performance continued on board the Elisabeth boat of the captain Carlo Dernini in the port of Carloforte, in the Island of San Pietro, off Sardina.
