Getulio Alviani (5 September 1939 in Udine, Italy – 24 February 2018 in Milan, Italy) was an Italian painter based in Milan. He is considered to be an important International Optical and kinetic artist, and created dynamic art which interacts with the viewer. He started exchanging ideas with artists like Julio Le Parc, François Morellet and Enrico Castellani, actively participating in the activities of the so-called G.R.A.V. (Groupe de Recherche d'Art Visuelle) in Paris. In 1962 he moved to Milan, where he became friends with Piero Manzoni and Lucio Fontana. In 1965 Alviani took part in The Responsive Eye at MoMA in New York, together with other artists associated with Kinetic and Programmed Art. Among his works, the best known are the "Superfici a testura variabile" where the polished aluminium reflects the light in different hues according to the angle at which they are viewed.
