About the algorithm:
Each drawing consists of two overlaying related structures.
The first structure is a grid which forms a matrix of squares.
The second structure is formed by moving the four sides of each of these squares
within its square according to global systematic rules. Different global patterns are created by defining the amount of movement of the sides within each squares.
