Seal of a Secret Society Tessellation

I was inspired to design the molecule of this tessellation after spending a lot of time analyzing various designs of Shuzo Fujimoto’s stars. Since pleats in the back are symmetric, you can rotate each individual symbol in 60° intervals, independently of other molecules.

The picture of the front side of the model demonstrates how complex a topic color is. Since the sheet is painted rather than made from colored pulp, at a few spots the paint wore off, showing the white underneath. I painted these spots over with a black permanent marker. Despite being black just as the paper, you can easily notice these spots: the surface there is shiny and stands out despite theoretically being the same color.

This model is folded from a duo-color back-and-white sheet of Nihonshi paper, a rare example of me folding tessellations from duo paper.
