Czech painter Zdenek Sykora, who was one of the first to use computers for his geometrical paintings, has died aged 91.
Sykora's aide Veronika Hudeckova says he died at his home in the town of Louny on Tuesday evening.
Born Feb 3, 1920, in Louny, Sykora's style gradually developed from landscape paintings in the late 1940s to geometrical abstract structures. In the 1960s, he became one of the first artists in the world to use computers to help him create geometric abstract paintings.
Later on, Sykora turned to a less strict system of line paintings with lines of color moving across large canvasses in random directions.
His paintings are owned by galleries around the globe, including the Pompidou Center in Paris.
