Found this motif by clicking the link on interaction lab recitation website.
Really like the diagram and thought it would be easier to draw on processing by drawing four rectangle and split equally and draw 15 lines in each.
My rough sketch
my code:
int s = 20;
strokeWeight(4);
size(600,600);
rect(0,0, width/2,height/2);
rect(width/2,0, width/2,height/2);
rect(0,height/2, width/2,height/2);
rect(width/2,height/2, width/2,height/2);
line(s,0,s,width/2);
line(s*2,0,s*2,width/2);
line(s*3,0,s*3,width/2);
line(s*4,0,s*4,width/2);
line(s*5,0,s*5,width/2);
line(s*6,0,s*6,width/2);
