Hands enter the frame, working together to rotate an image, separating it from an identical image on the layer below. As one set of parallel lines rotates against the other, the combined image appears as a moiré pattern: a row of elongated diamond shapes that shorten and multiply. Hands continue to rotate the image, returning through diamonds into long, angular shapes, and finally back to parallel lines. The sound matches the visual illusion—harmonic overtones are gradually added as the image becomes complex, removed as the image returns to simple alignment, and silenced when the lines are offset and blacked out.
