## Origami Menger Sponges

1. Begin with a cube.
2. Shrink the cube to 1 / 3 of its original size and make 20 copies of it.
3. Place the copies so they will form a new cube of the same size as the original one but lacking the centerparts, (next image).
4. Repeat the process from step 2 for each of the remaining smaller cubes.
After an infinite number of iterations, a Menger sponge will remain.

The Menger Sponge is a fractal particularly appealing to modular origamists, for two reasons: it can be made out of Sonobe modules (the very first “brick” that every origamist learns), and given its fractal nature, it can be expanded forever and ever. What follows is a list of origami websites on this fascinating structure: Continue reading Origami Menger Sponges
