OBSERVATION 022
折り
Ori — Fold
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.
The more it folds, the more the pleats stand.
The more it opens, the flatter they lie.
The number of folds does not change. Twenty-four, neither more nor fewer.
What changes is only how far each one faces us.
Closed all the way, every face turns edge-on and becomes a line.
Opened all the way, every face turns toward us and becomes one sheet.
The same paper, by orientation alone, is a line and is a surface.
Read and verify the equation
(i, t,
k = i % 24, m = (i / 24 | 0), u = (m % 60) / 59, v = (m / 60 | 0) / 26,
O = 1.62 + .96 * sin(t),
a = ((k + u) / 24 - .5) * O - 1.5708,
B = sqrt(max(0, 1 - (O / 2.58) ** 2)),
z = (k % 2 ? 1 : -1) * (u - .5) * 17 * B,
r = 60 + 120 * v + z * .8
) => [200 + r * cos(a), 302 + 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
