Jacques Palumbo (born 1939, Algeria) began using computers in the early 1970s. This screen print, after a computer generated drawing, is based on a matrix of numbers. The artist constructed his research using a system of codified signs in which typographical symbols (letters of the alphabet, numbers and punctuation) were linked to corresponding graphical symbols. Palumbo used of a series of mathematical rules to explore the spatial relationships between the symbols. Such work shares its roots with much of the systems led art that was produced in the 1960s and the 1970s, in which ideas and process became as important as the object itself.
