[28 F, 42 E, 16 V] Aristotle hypothesized in the fourth century BCE that identical regular tetrahedra could fill all of space with no gaps or overlaps. In reality, as proven roughly two millennia later, it is not even possible to make a loop of regular tetrahedra connected face to face. This structure, made of prototype construction pieces designed to connect polyhedra in this way, is inspired by the fact that linked regular tetrahedral never quite close up, although they can very nearly align.
