This design by Shuzo Fujimoto is an early example of an iso-area tessellation, i.e. one which looks the same on both sides, apart from possibly rotations and translations. The way I arranged the molecules on the sheet results in a straight margin on the model and slightly different shapes formed by the molecules: a rotated square on one side and a rounded shape on the other. This does not negate the tessellation being iso-area since that notion applies to the tessellation understood as an infinite pattern covering the complete plane. When a finite number of molecules are folded on a finite sheet, certain anomalies arise near the margins, and can be used for aesthetic effect.
