The illussion of a three-dimensional cube is evoked by projecting a set of 12 straigh lines onto the two-dimensional drawing plane. Mohr dissolves the three-dimensional by taking away edges(lines) of the cube consecutively and observes the appearance of new, two-dimensional icons. Inaddition, he introduces rotations and other transformations of the cube to foster visual ambiguity and instability. The dynamics of this process and its visual invention are explored systematically, and each result is drawn as part of a cluster of images representing the complete set of combinations.
