Assigned to the apex of the tower associated with Code-keyed Structures, the geometry of the disc orientation exhibits striking parallels to the standard textbook models of electromagnetic wave propagation.

The cubodal model of basic electrodynamic phenomena begins with a representation of equal and omnidirectional electric field vectors emanating from a stationary point charge - by the cuboda's 12 innate radial lines emanating from its center point. In this sense, outer cubodal lines bounding the e-field vectors correspond to the directionless electric potential field.

In the cubodal context, the dual possibility of the charge's motion begets a new relationship between it and the plane orthogonal to it bounded by the potential field, with that field's directionless attribute undergoing transformation into the dynamically directional one of a magnetic field signified by the cuboda's central hexagon.

Charge motion in this context is also characterized by its pointedness becoming increasingly associated with the plane of the (tetrahedral) triangle it resides on, such that its position becomes less distinct, mirroring the uncertainty principle of quantum mechanics.

Electric field-vectors now emanate from the triangle's points to the magnetic vectors that together, with periodic dipole polarity reversals, oscillate in an outward direction defined by Poynting EM wave propagation vectors, in an expression of wave/particle duality by reason of their original manifestation as e-vectors emanating from a point charge. Interestingly, an expression of curved space applied to the vectors' 60˚ intersections transforms them to the standard depiction's orthogonal intersections by spherical projection.

The essential motion of the charge in this model suggests a 3rd and final cubodal wheel orientation addressed in Rocket Carrier, topic 4 of Extra-topographic Guidelines.
