What is the Sierpiński tetrahedron? The Sierpiński tetrahedron is a 3D shape made by cutting a big tetrahedron (a pyramid with a triangular base) into smaller ones and removing the middle part over and over again. This process creates a pattern that looks the same no matter how much you zoom in. What does the Sierpiński tetrahedron show us? It teaches us about self-similarity, meaning small parts of the shape look like the whole. It also shows how a simple set of rules can create a complex and d

At the end, change the direction of the folds for the last 5 triangles (4 to cover all the sides, 1 to lock by inserting it under the layers) | Jo Nakashima | Facebook
