Very interested in having this; hope you're still working on it. I like that idea, and hiding the swap behind the second hand is a good misdirection (I can't think of a better word atm), but would that not have some issues with say, dual-wielding? And for maps as well, considering the equip-able map (at least, the one I've got) is simply a shield relocated to a better position. Seems like you'd end up dropping the map in reality. A flick-open animation would probably be better, ran when the compass is "unsheathed". There's a mod that does this well. As for the ball movement, I've got nothing, but maybe a custom enchantment? As far as I know (which is little), the enchantments have their own mesh, which might be able to have some physics. But again, I don't know what I'm talking about. I'm just offering ideas, most of which I'm sure you've thought about already. I had the same idea before I found yours, and have since abandoned mine, as I know NOTHING of what I would need. My idea was a wet-compass. A metal or wood half-cup and smaller inverted glass half-cup inside. Filled with alcohol, and a leather strip around the base inside, to keep it in. A small wooden needle with a metal cap on one end floating inside, held in place by a small iron rod. The glass section would be held in place by some decorative metal work. I actually spent a day researching some compasses of early Europeans, and decided a wet compass would fit a little better than the traditional ones. I've made a general idea of the mesh already too.
