See the Shake turns a phone's slow-motion video of a running machine into a vibration diagnosis. Machine faults have vibration signatures. An unbalanced drum shakes once per turn, and a loose mount rattles at half that speed with a row of harmonics above it. Factories read these with accelerometers and a trained analyst. A small workshop has neither, but its technician carries a phone that films 240 fps.

Muse Spark watches the clip and picks the parts to measure, and SAM 3.1 masks them. Our code tracks each part's sub-pixel shake against the still background and plays the clip back with the shake magnified, so you can see the door bounce. Fixed rules name the fault from the measured peaks. Muse Spark explains it and suggests a fix, and code checks each claim it makes against the measurement before showing it.

On a digital twin with injected faults, the rules got 12 of 12 verdicts right, with 119 of 120 vibration components within tolerance. On a lab rotor rig fitted with displacement probes, the measured running speed was within 0.02 Hz of the probes on all 9 runs. On a real washing machine filmed at 120 fps, 95% of the door's vibration sat at the spin speed, which reads as imbalance. A run costs 5 to 10 cents and takes a few minutes. It's a web app you run locally, and recorded runs replay without an API key.

Built from scratch during the hackathon, Oct 26 to Nov 4. Pre-existing: open-source libraries and two credited clips.
