Thank you, Flashback! The diagram clearly shows a magnetic/wave-form interference pattern, with one tetrahedron as the magnetic North (the 3 arms marked by white triangles at the center) and the other tetrahedron as the magnetic South (the 3 arms marked by the dark triangles at the center) of the dipole that runs Earth's magnetosphere. Also visible in the diagram is the tiny dot INSIDE the point that the outside dots are above. From an HD physics point of view (pardon the pun), it is a clear reminder that 'exterior' electrical effects on Earth (like heavy-duty tropical storms/hurricanes) are triggered by internal HD-energy induction.

Peace,
