that a less intense or "cooler" heat affected them. According to this hypothesis, the reason that the stalks in a central tuft aren't laid is because no MASER Heat is sent out to make them supple, and at this point, the Wind quanta's "programs" are instructing them to "exit", not "lay".
When the Wind quanta do not leave via a central tuft, they exit "up the wall" of a Circle's perimeter. In this case, the packets of Wind spiral their way from the centre of a Circle outward to its perimeter, which pattern can be seen in the beautiful Galactic "S"-Spirals we've admired in many Formations [see Spiral-lay photo pg. 20, and storyboard panel 4, pg. 18]. Between the perimeter and the standing stalks immediately outside the Formation vibrates the SoundBarrier. As the Whirlwinds reach the perimeter, the impenetrable-to-Wind Wall of Sound redirects their "forward" progress from a horizontal to an upward-oblique direction. The angles of the perimeter stalks indicate the paths of the Winds' exit. Most Circles display these wispy, angled perimeter stalks.
Within a single Formation, stalks in localised areas along the circumference lean at the same angle, although the angle may vary even within segments of the same Formation. Moreover, the number of stalks within each group of perimeter stalks is (more or less) consistent within a single Formation. For example, in one Circle, groupings of 3-4 stalks along the circumference might all be angled at 60°; in another, groups of 15 or 20 stalks might be leaning at a 30° angle [see Perimeter Stalk collage, pp 24-25].
As the Wind quanta spiral upward along the wall of the SoundBarrier, they ultimately dissipate somewhere above the Formation. Perhaps they simply "run out of steam" and dissociate, or perhaps the SoundBarrier or the Silver Spheres absorb their remaining Energies.
