8CB smectic liquid crystal has been used surrounded by a glycerol matrix. This glycerol will not mix with 8CB but is used to provide some planar degenerate boundary conditions. Figure 3a represents the generation texture observed under crossed polars microscope which shows the presence of some hexagonal tiling of focal conic domains in the particular case where the ellipses are degenerated into circles and the hyperbolae into straight lines. In this situation, the Dupin cyclide layers become simple torii (see figure 4b). In Figure 3b, some simulation with the Apollonius tiling has been done with 4 generations of circles.
