A bench instrument that records how your hand actually moves. Scroll the specimen track with touch, drag, wheel, or arrow keys — the machine writes your velocity, acceleration and frame cadence as a temporal seismogram, replays it against a ghost cursor, and exports the trace as a real SVG.
Ready. Demo traces loaded in Take A and Take B.
Task: bring stratum to the centre reticle, then stop. The instrument records the whole approach.
Surface changes the friction and settle behaviour of the track. Record the same reach on two surfaces, then compare the traces.
Export writes a genuine vector SVG of the current seismogram to your downloads folder. Nothing leaves this tab.
