Rotated tile principle
French mathematician whose 1704 study showed how rotations of one divided square could generate remarkably varied ornamental fields.
Each hex picks one of two arc orientations. Adjacent edge midpoints join with 120° arcs so paths continue across the honeycomb.

Each hex picks one of two arc orientations. Adjacent edge midpoints join with 120° arcs, so paths continue across the honeycomb instead of dying at the cell wall.
