Early algorithms (1969-1973)

During these years, Mohr introduces into his work a logical and automatic construction of pictures, using algorithms for the first time. The artist writes computer programs and obtains drawings realized by a computer controlled drawing machine (plotter). With a choice of different line characteristics, an alphabet of arbitrary generated elements is created. Individual algorithms are invented for each work from which all forms and structures are solely generated. The algorithms are built from imposed as well as from random selection principles which the artist called “aesthetical-filters”.
