Five shapes. Five elements. Five strings on the instrument of the cosmos. Each one is dual to another :: exchange the faces and vertices, and a sibling emerges from within. Together they form a complete vocabulary of form. Plato heard them. Now touch them.
:: Press 1–5 to move between the five shapes. These are the only five possible :: Euclid proved their completeness in Book XIII of the Elements. Each transformation is a conversation between geometries :: pure becoming.
