Similar Orientations Associate
I've used Empire Star blocks for this example because they are asymmetrical. As a result I can place some horizontally and some vertically.
You see the two two kinds of Empire Star blocks as being different because they are different. All the horizontal blocks are one grouping. All the vertical blocks are another grouping. The horizontal blocks associate. The vertical blocks associate.
However, the connection is not very strong. How can I make it stronger?
