A fan‑shaped regulator plate and a set of screws turn into a stern, almost totemic face, while preserving the metallic texture of bronze against a warm ochre ground.

Two toothed wheels with pink ruby bearings play the role of alert eyes, and a blue wedge—the “nose”—with a slotted screw above it looks like an exclamation point, linking the precision of regulation with emotional intonation. A row of tiny screws—rivets along the “forehead” traces an arc of tension: the mask seems to quiver between calm and surprise, showing the range of human feelings.
