After dedicating research and time to the Fushimi Cube last week, I want to introduce you to the even more magical Fujimoto Cube. As the name already says, it was discovered by the grandmaster of origami, Shuzo Fujimoto 藤本修三先生. You can find the diagram in the following books: Invitation to Creative Playing with Origami by Shuzo Fujimoto, p. 6 (original 1982, reprint 2007); NOA magazine Nr. 472; Origami Project F – Twist Folds by Shuzo Fujimoto and Origami for the Connoisseur by Kunohiko Kasahara.
A side note to Project F プロジェクトF books by Shuzo Fujimoto: Since the passing of Sensei Shuzo Fujimoto three origami specialists have taken on Project F to summarize and republish his old works: Satoko Saito, Niwa Taiko
What’s so Special About the Fujimoto Cube
With only a very simple (with simple I mean incredibly well thought off!) crease pattern (based entirely on geometry) you can collapse the Fujimoto Cube. The process of collapsing is almost like magic, as you slide the outside layer along the inside layer. Once they reach the point where they are supposed to be, the cube locks into place. The locking mechanism itself is unbelievable, as the overlap that normally occurs in the twist fold, hides inside between the top and inside layer of the box. If you don’t know what I mean with this, fold any single-sheet box by Tomoko Fuse. The overlap is normally used to create decorative lids in her work. Also, the “good” side of the paper shows inside and outside.
