This work phase
(1977-79) is based on the four-dimensional hyper-cube. In this
work the graph of a hyper-cube is the basic generator of signs.
This graph is a two-dimensional representation of the hyper-cube,
indicating relationships between points, lines, squares and cubes,
inherent in this structure. A global structure is generated either
by combinatorially selecting lines from the cube or by showing
connecting paths between 2 given diagonally opposite points on the graph (diagonals). A 4-d hyper-cube has 8 pairs of diagonally opposite points.
A "diagonal-path" is the connection of 2 such diametric points through the network of edges of this complex structure (there are 24 "diagonal-paths" for each of the 8 diagonals).
