Three-colored two-dimensional tilings like textile designs have been obtained by means of the self-organization of ABC star block copolymers. These tilings are well described by Archimedean tilings studied by Kepler. Recently, an Archimedean tiling (32.4.3.4) having more complex molecular environments was found. This structure is known as the \sigma phase in the Frank-Kasper complex alloy family. Furthermore, it is an approximant of dodecagonal quasicrystals.
