In the Cubic Limit work series, Manfred Mohr introduced the cube into his work as a fixed system with which signs are generated. In the first part of this work phase (1972-76), an alphabet of signs is created from the twelve lines of a cube. In some works, statistics and rotation are used in the algorithm to generate signs. In others, combinatorial, logical and additive operators generate the global and local structures of the images.

In this particular drawing there are twelve steps taken that translate one sign into another. At the top is a cube drawn with thin lines. Gradually and step by step, this sign intersects with a second rotated cube which is drawn with thick lines – until its final transformation at the bottom. To this end, each middle step was calculated by a computer using an algorithm written in FORTRAN by Manfred Mohr.

The ink drawing in this work was computer-controlled using a Benson plotter- although the paper on which it was made is sprocketed along the sides (and therefore unconventional for use with a Benson plotter).
