This is the final project for Coursera course I’ve completed in December 2020.<\/p>\n\n\n\n

The process is summarized as follows: a network of points on a plane formed the first squares. The grids of the upper squares were formed by the tokenization of a random number and several “If conditions”. Eventually, the squares were swiped together.
I put the code here to find out exactly what I did.<\/p>\n\n\n
