Aleksandar Srnec (1924, Zagreb – 2010) was a Croatian artist. His work includes painting, sculpture, kinetic and luminous art, animated movies and graphic design. He studied at the Akademija likovnih umjetnosti u Zagrebu, Zagreb (1943–1949).
In the period from 1948 to 1951 he collaborated with Vjenceslav Richter and Ivan Picelj on designs of Yugoslav exhibitions and pavilions at fairs in the country and abroad (Book Exhibition of National Republic of Croatia, exhibition Industry of NR Croatia in Zagreb, exhibition Highway of Brotherhood and Unity in Zagreb and Belgrade, projects for Yugoslav pavilions at fairs in Stockholm, Vienna and Hannover). Together with Ivan Picelj, Božidar Rašica and others he was a member of the group of artists and architects EXAT 51 in 1950-56. In the then dominant climate of socialist realism the group advocated abstract art. With his works in 1953 he participated at the first exhibition of abstract art in public venues in the former Yugoslavia and the rest of the Eastern bloc, held in the Croatian Association of Architects in Zagreb. He transferred his mostly linear compositions during the realization of the object Prostorni modulator [Spatial Modulator] in 1953 from images to the third dimension, and in 1956 his research in the field of sculpture included movement. His experience of working on animated films in Zagreb School of Animation (1959–1960) motivated him to examine the effects of light in motion. Starting from 1962, and most productively in the period from 1965 to 1971, he implemented it in a series of lumino-kinetic objects that represented the most radical innovative strides in visual arts. Luminoplastika [Lumino-plastic] presented in 1967 in the Student Center Gallery in Zagreb is the first representative of its genre in Croatian art, and lumino-plastics were also presented at the exhibitions Nove tendencije [New Tendencies] in 1963 and 1973.
