So I was thinking you might want to consider adding a builder-machine - whatever is slotted into it it builds in front of it. Or maybe this could be an advanced robot, into which you could even load blueprints (one of the stretch-goals) and materials and it would go around building what has been set into it.
See, my goal is to make some Von Neumann goodness
Not that I could myself, but someone surely would do it! Self-reproducing machines, isn't that a challenge? Think of what could be done with that + some basic logic operators...a bit like some of the incredible redstone machinery in minecraft, but better, because with the replication building part!Angelic
