After I designed this tessellation, I learned that Shuzo Fujimoto had designed the same thing about 40 years earlier. This was the first time such independent invention of a model happened to me. Later I found out this actually happens once in a while, especially in the world of geometric origami.
This tessellation, one of Fujimoto’s translucent designs, is a modification of square twists by pursing, and very simple to fold. The work presented here contains more molecules than my previous folds.
