Supplementary Figure 1 : Graphical illustration of the rotate-and-mirror method for constructing a 2D level-3 hierarchical structure. Square rigid unit or assembly from even levels is rotated counter-clockwise firstly and then mirrored (about M planes) to create assembly for constructing the next level hierarchy. Assembly from odd levels is rotated clockwise and mirrored again to create higher level hierarchies.
