He is the greatest Italian video artist: the focus of his artistic research is on the analogies between liquid surfaces and the image of the screen that almost always concerns natural elements: water, fire, earth, lava, in the form of installations, films, videotapes and performances. He participated in the Venice Biennale in 1970, 1972, 1986, in 1987 in Documenta VIII in Kassel, in 1998 at the Guggenheim Museum Soho in New York and at the São Paulo Biennale. In 2000 he created the Italian pavilion for the Expo in Hannover, with a monumental 44-meter-high installation “Mare Verticale” and in 2005 he participated with a new version of Mare Verticale at the 51st Venice Biennale. Several contaminations with theater, fashion, scenography and installations that increasingly amplify the extreme technological possibilities of electronic, visual and technological reproduction.
