In 1961 he was invited to the Zagreb exhibition "Nove Tendencije", together with other artists working along similar lines and exploring the opportunities of a dynamic art which interacts with the viewer.
In 1962 he moved to Milan, where he became friends with Piero Manzoni and Lucio Fontana, who was very interested in his works and bought some of his "surfaces".
In 1965 Alviani took part in The Responsive Eye created by curator William C. Seitz at MoMA in New York, together with other artists associated with Kinetic and Programmed Art.
He also exhibited at the Milan Triennale, the Kunsthaus Graz, Palazzo delle Papesse in Siena, Academie de France in Rome, the Buenos Aires Biennale, the travelling exhibition "Light, Movement and Programming", and the Rome Quadriennale.
Among his works, the most appreciated by the market 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.
