I find it more like the feeling of having sorted out my wardrobe (folded things and thrown out old clothes, I hate doing this despite feeling better afterwards). Or a mix of that and say building a good looking Lego MOC from a limited set of pieces. But only for some things - I have several self-contained python scripts that give me this feeling. Sometimes fixing a bug in a clean way. Other things - Android apps for example - tend not to give me this vibe. They feel more nebulous and "unfinished", like it's a miracle they work at all and will break at any moment in ways I couldn't understand.
