So I downloaded this just to read the code real quick and I have to say it was worth it.
Not so much the mod itself as most of my enjoyment of this masterpiece came from reading the readme, license and changelog, bundled in the download.
That said, I think it lacks some kind of backstory as I am probably not going to use this pinnacle of modding without knowing the details about it's legendary origin, that I'm sure it has. I think it would be a shame for all the effort to go to waste for such a lame reason.

Overall - 5*, would readie again.

Renames the undeground pipe to.. underflowies.. and the description of the item to the description of this mod... and the readme has some more silly words about the "grand scope" of the mod... as a joke, I don't think it's a very good one, but maybe there's an actual history behind it. Not that I care enough to go looking =P
