yeah, polarization. Just saw it displayed in a museum. Making light go in
one dimension/plane only. Light NOT over the ranges.
Another metaphor with reach. A beginning of a crystal palace, so to allude.

The key to sunstone navigation is polarization, a process that filters
light rays so they can only move in one plane. Sunlight starts out
oscillating in multiple planes, but atmospheric particles create concentric
rings of polarized light around the sun, even on cloudy days.
