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 ( 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.
