Menger Sponge Fractal Unit | Made with (and of) Paper |

"The Menger Sponge is a 3-D analogue of the so called Sierpinski Carpet. The Sierpinski Carpet and the Sierpinski Triangle are both well known examples of fractals. A Menger Sponge has to be built as one piece, from beginning to end, rather than assembled from individual cubic units. Similarly, each color paper had to be applied along the way to the white card stock "core" as the construction expanded."
