“Generated Art” may sound a bit stupid as all works of art need to come out of something. Everybody will confirm that this is true for a painting. But it is true for a piece of conceptual art as well, as even this needs an idea, a description, a path of distribution and more.
A very specific topic of generated art deals with products which result from computational processes.
This has a long tradition: as early as 1800, creative artists such as Justinus Kerner, Alexander Cozens, or George Sand allowed chance to take control over their works.
In the 1960s, Vera Molnar, Frieder Nake, and other computer pionieers used algorithms to research variations of creative processes. Later, Gerhard Richter calculated the design draft for the windows of the Cologne Cathedral by an algorithm which specified colors according to his predefined rules.
Nowadays with graphic programs one may create images in several variants originating from only a few rules. Now, the artist’s act consists of designing such rules and specifying valid works of art.
This page shows some results of such computational processes after creation and selection.
