I'm not in any way a great artist, but if you like, I could try and help you out.
I would assist in covering 3 parts:
Vanilla/base game
Bob's Stuff
Angle's Stuff
It won't be pretty
All i would need is to know the limitations and the like.
Like what is the dimensions of a typical image of this.
Now I have NO idea where to begin or end, or how to go about doing this, but this could be made into a full fledged mod for Factorio covering a huge amounts of the game and other mods.
But lets start in the small stuff...
I'll be using Gimp, it what i know and it has worked for me for YEARS.
What is the file type to save as and all that...
