Author's Note: I developed a odd fascination with the Menger Sponge, and what do we do with such things? Build them in Minecraft! I build this one back in the Beta in single player survival, and this is actually the biggest that could be made back then. It's so large that only 2 more blocks can be placed on top of it, and it extends 21 blocks below sea level. I placed every block old school, one by one, no fly mods or anything like that aside from inv-edit, which i used to get the material. Coolest garden ornament ever. :)
Feel free to google it, it's fascinating. Please also look at the WIP pictures. :)
