Minecraft Menger Sponge (3.2 million blocks!!)

It's a basic level 5 Menger Sponge built out of 3.2 million sponge blocks. For those of you who don't know, a Menger Sponge is a fractal made out of cubes. Imagine a Rubik's cube where you take all the center pieces out and the piece in the very center as well. That's a level 1. Now take 25 of those and build a larger cube. Take all the centers cubes out. That's a level 2. Repeat until you are at level 5.
