float box_size = 11; 
float box_space = 12; 
int margin = 7;

// Draw gray boxes 
 
for(int i = margin; i < width-margin; i += box_space) { 
  for(int j = margin; j < height-margin; j += box_space) { 
    fill(255 - box_size*10); 
    rect(j, i, box_size, box_size); 
  } 
  box_size = box_size - 0.6;
