The only purpose of this mod is to provide a node that looks like an Unknown Node but actually is not. I think the texture is worth it.
You can craft this node by arranging cobblestone in the shape of an U into the crafting grid:
C C
C C
CCC
Mod dependencies: default (for crafting, should work with all modified 'default' mods.)
The mod also adds basic stairs and slabs like the ones found in default Minetest Game.
Compatible with moreblocks: Will register stairs, slabs and microblocks when moreblocks is present.
Interesting
Well, that's an interesting feature to add fake unknow item.
Good compability with moreblocks.
