Here's what I have so far. Although the analogy is imperfect (the dynamics and "current flow" are atypical) it suggests the idea behind an electrical generator, with its stator, rotor and shaft. The "rotor" (Princess) picks up the "current" from the "stator" (the associated Prince in the orbital "ring") and concentrates it, delivering it to the "shaft" (Ace) for transmission to the "battery" (world of matter). A metaphysical "induction coil" is another thought, with the Knight/Queen/Prince ring as the "outer winding" and the Princess as the "inner winding", while the Ace acts as the "core."
To get around the complexity involved in showing a fully 3D structure, I did this as a "vertical slice" showing the single central degree (15 Aquarius) within the Princess of Sword's quadrant. The picture also makes me think of a pennant on a flagstaff that rotates through 360 degress of the sphere. But I like the "electrical generator" idea better since it more fully expresses how I see the dynamic.
Note that I left out the Major Arcana this time around, but will examine how to best fit them in at the next (hopefully "prettier") iteration.
ETA: In retrospect, that "orbital ring" should really be depicted as a "stacked" three-tiered design (Knight/Queen/Prince in descending order), similar to the Hierophant's crown and scepter in the RWS image. That way, all 12 of the remaining court cards could be loaded into the 360 degree model.
.... and the whole of the Southern celestial sphere is left out ? (similar to the GD model )
