Station YOU·01 — continuous record
TREMOR
Every seismograph waits for the ground to shake. This one waits for you. Move the cursor, spin the wheel, strike a key — the stylus answers in real units and the paper keeps rolling. Hold perfectly still and watch it flat-line.
01 · Second personWhat the needle knows
It knows nothing about who you are. It cannot read your name, your face, or your thoughts. It reads only your hand — the velocity of the cursor, the impulse of a click, the jab of a key, the roll of the wheel — and turns that motion into a signed deflection of a virtual galvanometer, the same physics a real drum seismograph uses to record a distant quake.
So the line you are drawing is not a decoration. It is a measurement. Fast, buffeting motion writes a busy band of oscillation; a single click arrives as a clean damped spike, ringing down like a P-wave; and the moment you stop, the stylus falls back to the baseline and the paper records your stillness as faithfully as it recorded your restlessness.
02 · UnitsCalibrated, and forgetful
The scale is honest to itself. One division is 6.5 µm/s of apparent ground velocity; the portrait tallies your peak, computes a local magnitude on a log scale, and times your longest genuine stillness to a tenth of a second. Nothing is stored — refresh the page and every reading is gone. The drum keeps no record of you once you leave; it only ever describes the person moving it right now.
That is the whole trick of a second-person instrument. There is no content here to consume, no scene to admire — only the loop between your hand and the line it leaves. Go still and it flat-lines. Move and it lives. You are the only signal it will ever receive.
