A broad oak tree with a twisted black trunk grows out of an open book, its pages fanning out in fine engraved lines. Three square frames with ornate inner patterns sit among the branches and trunk, disguising the finder squares as carved wooden panels. The data modules are carried by the knotted roots, bark swirls and small stacked book shapes in the trunk. Solid black masses against the white background keep the pattern readable, while stippled leaf clusters add texture without crowding the center.
