So here is a mine wall as it stands right now:

Here is my version of how it could look with iron ore in it (Yes that is the smudge tool lol)

I just thought that this would be a cool little addition to the game, and each wall should have a different model than the one beside it (Maybe make 4 or more models so no 2 walls that are adjacent to each other are the same.)
And of course this isn't a game changing idea but aesthetics are always nice
