Eight strands. One cord.
The carriers exchange places, the bobbins pay out, and the crossings travel into the finished braid.
Follow the thread.
From a moving bobbin to an exposed crossing. Two 18-second films rendered from the same geometric model you can rotate, pause and inspect yourself.
72 carriers. 576 wires.
Eight parallel ends per bobbin, guided separately into crossings around a central cable.
Both films are silent, with captions built into the picture, in vertical 1080 × 1920 format. The wire geometry is checked at the scopes described in the mechanism audit. Carrier handoff and tension hardware remain in development; these are not recordings of a working physical build.
Try the carrier guidance experiment or tension calibration board. The build guide includes the prototype files and what remains to be tested.
