Abstract art built from purely visual elements such as lines, planes and color, with no reference to the outside world. Theo van Doesburg named it in 1930, and Max Bill developed it after him.

Andreas Gysin, AGH on Glorifying the Computer
New Tendencies was all about the mechanization of art and programmed painting of the François Morellet, and they were very inspired by this Constructivist style and had a very concrete art look.
Peter Bauman, Michael Spalter on 1960s Computer Art
