Tony Smith created large scale geometric bronze sculptures that similarly explore the tension between solid mass and negative space through precise angular forms. His minimalist approach to architectural abstraction and use of dark patinated bronze surfaces closely mirrors the formal language of Hex.

Noguchi's sculptural practice embraced geometric abstraction in bronze and stone with an architectural sensibility that treated interior voids as equally important as solid form. His work shares the same meditative interplay between positive and negative space that defines Ladato's hexagonal composition.

David Smith pioneered American modernist sculpture through geometric metal constructions that investigate spatial relationships and architectural structure in ways directly comparable to Hex. His use of industrial metal techniques and abstract geometric language aligns closely with Ladato's dark patinated bronze minimalism.
