On July 1 of 1989, in Rome, at the Metateatro, it was staged  the art opera 1992 Christopher Columbus -Voyage in the Art Planet, produced by Stephen DiLauro, directed by Tanya Gerstle, with music by Giancarlo Schiaffini, in which as closing act it was performed the closing of Plexus into a black box. It was performed by Willem Brugman, Sara Jackson, Stephen DiLauro, Tanya Gerstle, Maria Pia Marsala, Antonio Caboni, David Boyle, Matthew Schwartz, Sandro Dernini, Giancarlo Schiaffini, Fabrizio Bertuccioli, Micaela Serino, Loreto Papaia, and Annetta Ducrot. Paolo Maltese wrote the program preface. The storyline was a self-discovery journey towards the discovery of the planet of art.  Willem Brugman was Columbus, Sara Jackson and Stephen DiLauro performed Queen Isabel and King Ferdinad. The Druid David Boyle was the owner of an old Iceland map,  rolled and bounded with a Plexus Campboll Soup Can's label: "La Mappa Bona (The Good Map) to arrive to the planet of art. The art route was designed by the blueprint of a computer retina device developed by George Chaikin from his Haddamard Matrix, dedicated in 1985 to Ralston Farina’s TimeArt and freely distributed to the audience at the 1986 Plexus art slaves auction at CUANDO. The discovery of the art planet was led by a magic unicorn, played by Willem Brugman, with the shaman Antonio Caboni, while Maria Pia Marsala as Black Princess with Tanya Gerstle as White Goddess danced and played with the Earth globe, with Loreto Papaia on stage video recording the action. Sandro Dernini as Plexus 23s, with Annetta Ducrot, Giancarlo Schiaffini and Fabrizio Bertuccioli, performed the arrival of the Plexus voyage.  With Paola Muzzi, one of slaves of the cultural slave market made in Rome by the LIACA in 1979, he presented the Plexus Art Slavery Manifesto.  A music note performed by Giancarlo Schiaffini with his tuba inside the small wood black box symbolically represented the closing of Plexus in the Black Box, placed inside  the cylinder box Made in the 80s for the 90s.  Then, the audience was invited to sign the Plexus Boxing Ring for Freedom in support to the continuation of the art journey to the House of the Slaves in Goree, towards the discovery of new world(s), with no slaves. The end was made by participants asaying their own name while crossing the door painted by Fabrizio Bertuccioli with a heart and the words “Open the door of  heart to go in the future.”
