These two images are meant to rhyme, visually. Let me give you some background.
One of our teachers has occasion to make the origin of our Caltrop Coordinate System (CCS) not its center of gravity, but one of its tetra tips, call it Blue. Blue origin.
We also want to orient our tripod tower vis-a-vis the Earth in an obvious way, akin to that of a radio broadcasting antenna. Call that vertical spoke Green. That leaves two more feet on the ground, aside from Blue.
Looking from Blue, with Green vertical, have Yellow be on the left, Red on the right. We call this "the bridge" or BRYG tetrahedron (or 4eyes).
The idea is Blue is the actual point of origin, where the record gets played as it were, after which it gets pumped out through the Green tip, high in the sky. Yellow and Red anchor with Blue.
Naturally the two below rhyme as well, and sound the same themes. The camera angle is looking down a little, from a drone point of view. The background is not Earth's surface unless we see that as ice,
In terms of the CCP, closest cubic packing, there's the question of how we want it centered, on a ball or on a void.
Where six balls hug a central void, the CCP might be anchored. Likewise the voids at the centers of four balls form two interwoven CCPs. That's four CCPs in all: ball centered, or void centered in three alternate, not-overlapping patterns.
By "not-overlapping" we mean none of the four IVMs share balls with one another, even as they co-define their shared lattice.
We say Yellow stands for Sun, in the background, providing power, while Red could stand for blood and what's biological (burning, metabolic), the life that covers our Blue ocean planet and turns it Green.
