Plotter drawing ink on paper
20 x 26 in / 51 x 66 cm
Mohr calculated this particular picture using a program that he wrote in the FORTRAN language. Using a choice of different line characteristics, an alphabet of arbitrarily generated elements depicts the surface of an electronic circuit in columns. Part of Mohr’s early algorithmic work phase (1969-72), it emphasizes a “formalism” of the software medium: logical and automatic construction of pictures. In this work phase, the left-to-right linear composition is also influenced by Mohr’s observation of the way a computer-controlled drawing machine (the Benson plotter) drags ink across the paper, as if it were written in a script. Typical of this phase, the piece links line to language, process and conceptual systems.
