Play with it
40000 points ・ 10s per turn

Press the picture to reduce the points.40,000 → 625 → 40 → 1. Restore at any step.
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.

Fifteen of them, growing smaller into the distance.

The pillars are not upright. They lean inward as they rise.
The lintel curves up at its ends.
The middle is not sagging; the ends are lifted.

The gaps look tighter further in,

What you are seeing is not the gates.
It is the hollows made between them.
