Recreation of the art

I really like squares. Here are some squares:

int square_size = 100;

void setup () 
{
  size (800, 800);
  background(255);
}

void draw () 
{
  noLoop();
  background(255);
  draw_squares();
}
void draw_squares()
{
    for (int i=0; i < width; i+=square_size) 
  {
    for (int j=0; j< height; j+= square_size)
    {
      strokeWeight(8);
      float randomizer = random(5,15);
      rect(i, j, square_size, square_size);
      for (int k = 0; k<random(3,6); k++)
      {
        strokeWeight(2);
        
        rect(i+(k*randomizer), j+(k*randomizer), square_size-(k*20), square_size-(k*20));
      }
    }
  }
}

Here is what I’ve got as a result:
