Computer Art
Term formerly used to describe any work of art in which a computer was used to make either the work itself or the decisions that determined its form. Computers became so widely used, however, that in the late 20th century the term was applied mainly to work that emphasized the computer’s role. Such calculating tools as the abacus have existed for millennia, and artists have frequently invented mathematical systems to help them to make pictures.

Computer Art
Term formerly used to describe any work of art in which a computer was used to make either the work itself or the decisions that determined its form. Computers became so widely used, however, that in the late 20th century the term was applied mainly to work that emphasized the computer’s role. Such calculating tools as the abacus have existed for millennia, and artists have frequently invented mathematical systems to help them to make pictures. The GOLDEN SECTION and Alberti’s formulae for rendering perspective were devices that aspired to fuse realism with idealism in art, while Leonardo da Vinci devoted much time to applying mathematical principles to image-making. After centuries of speculations by writers, and following experiments in the 19th century, computers began their exponential development in the aftermath of World War II, when new weapon-guidance systems were adapted for peaceful applications, and the term ‘cybernetics’ was given currency by Norbert Wiener. Artists exploited computers’ ability to execute mathematical formulations or ‘algorithms’ from 1950, when Ben F. Laposky (b 1930) used an analogue computer to generate electronic images on an oscilloscope. Once it was possible to link computers to printers, programmers often made ‘doodles’ between their official tasks. From the early 1960s artists began to take this activity more seriously and quickly discovered that many formal decisions could be left to the computer, with results that were particularly valued for their unpredictability. From the mid-1970s the painter Harold Cohen (b 1928) developed a sophisticated programme, AARON, which generated drawings that the artist then completed as coloured paintings. Although the computer became capable of that task as well, Cohen continued to hand-colour computer-generated images (e.g. Socrates’ Garden, 1984; Pittsburgh, PA, Buhl Sci. Cent.; see fig.).
