The most readily visible plane figures that you notice are triangles and hexagrams, the Star of David. Note how they are nested just like the cubes. If we keep the center point and the six outer points the same, while moving the inner ring of six points 30 degrees (to positions on the diagonals of the hexagram that are between the circles) we get an entirely different, well-known figure.
Compare to the Tetractys (below). See how the figure with the dots above is composed of two of these images on top of one another, which actually only adds three dots to the initial 10.
The arrangement of stars in the Great Seal is a compliment of Metatron's Cube. Note that this figure does not accomodate the three axiis of the "six directions in space". Note also the twin "Y" figures formed by the eagle.
