You can use small shapes and put them together to create a collective, larger shape. It is kind of like a collage but made up with shapes instead of pictures. Each of the smaller shapes are connected by a kind of rod that allows them to pivot in different directions around this central point connect each piece. This gets tricky when you move once piece and it moves a bunch of different pieces too. The shapes will turn a darker color when you have them in the correct positioning. See how your skills are on matching up.
