I've always liked building systems where the joints are visible: legos, Minecraft. Lately I've been thinking about the process of learning how to find the joints in systems where they're less visible. Of 'carving at the joints'.
The concept
Apparently Plato talked about "carving nature at the joints". I think my recent reference is the show Delicious in Dungeon, where they explain how to cut and prepare dungeon monsters into unlikely meals. The show has a lot of fun with the instructions reveal, where something that looks inedible is made appetizing through a precise set of steps.
