In “Divisibility”, the cube is used again as a fixed structure to generate signs. The cube is divided into four sections by a horizontal and a vertical cut. Four independent rotations of a cube are projected onto the corresponding quadrants created by the cut. In order to visually stabilize the structure, two diagonally opposed quadrants (top right and bottom left), contain the same rotation. In the first part of this work phase (1980-84), the “four-cut” is the basic structure with which the “out-lines” form shapes and the “in-lines” form signs.
