I wanted to design a side table using a single material and single shape. First I designed a triangle made of wood. Ok, there is no way this triangle can stand on it’s own nor carry anything. Then I designed a second triangle fairly smaller and turned it upside down and joined them together. Now it thad potential to carry something and stand on it’s own. I made more triangles and joined them together and there it was. A coffee table made of triangles. One shape, one metarial.
