Add another 9 cells with similar linkages and it models a two sided piece of paper. With a couple of connections between the front and back cells, it now represents a tube. Arrange those connections differently and it becomes a mobius strip instead. Not to mention the silly things you can do with unidirectional links. I could give more examples, but it should be pretty obvious this can represent any 2-D, 3-D or even n-D layout. (Except perhaps weird sub-atomic spin models where you must go around a closed loop twice to get back to where you started.)
