const ARMILLARY: [(Vec3, [u8; 3]); 2];Expand description
The armillary rings circling the largest body: each is drawn around an axis the frame tilts differently, so the two cross twice and each passes in front of the body it circles on one side and behind it on the other.
The colour is a saturated ink washed to WASH_ALPHA; the rings are drawn
wider than the orbit so their crossings read at a glance.
