Press the picture or the button to reduce the points.40,000 → 625 → 40 → 1, then back to 40,000.
At fewer points, dots grow and trails linger to help you follow their paths.
“Listen” maps the displayed points to sound.Changing the count rebuilds the sound.
Released from anywhere, they fall to the same ring.
A point started outside and a point started inside arrive at one place.
The falling slows as it closes in.
So the last small distance is where it stays longest.
That is why, from far off, it looks stopped.
The ring is not a point. It has width.
Even inside it, there is still swaying.
The range within which swaying does not take you out is what we call being settled.
Watching the return, I think of anxiety.
What would have to change for another destination to appear?
Read and verify the equation
(i, t,
j = i % 120, k = (i / 120 | 0) / 333,
w = (k * .30 + t / (TAU * 2) + (j * .618034 % 1)) % 1,
R0 = 30 + 168 * (j * .754878 % 1),
V = 92 + 4 * sin(t),
r = V + (R0 - V) * exp(-4.6 * w) + 6 * sin(w * TAU * 3 + j),
a = j * 2.39996 + w * 1.35 + t * .5
) => [200 + r * cos(a), 200 + r * sin(a)]

The same point number and time give the same coordinates.
Trails and the appearance of points depend on rendering settings and the device.
The button above takes the equation out as it is. To count it again yourself:
pbpaste > f.txt && printf %s "$(cat f.txt)" | shasum -a 256
