Step 2. Construct lines from each corner perpendicular (right angles aka 90 degree angles) through the main diagonals. These are called reciprocals. The intersections may be seen as good candidates for focal points since they have lines emanating from them at right angles. to each other on the diagonal. They are more dynamic than a checkerboard grid static in appearance.
