The Painter
A lot of blocks have Smoother/Rougher variants, with the Smoother usually being a type of brick. Aetherium Bricks vs. Aetherium Blocks being a good example. This would be a simple recipe just using the Cogs and Stone at a furnace to create Cog Bricks, and a respective wall for them as well, to be a smoother brick variant to them. I don't have any concept sprites down yet, but I might make one soon. I'm thinking it'd match the Cog's Steampunk Furniture with a Golden Surface on the top and a Gray/Green underside comprising most of it. It'd have no other purpose than just aesthetics, but it would be great for any steampunk builds to mix and match with the normal cogs and it's furniture.
