Clever! Now, if you had it animated so the gears meshed, turned, and served some purpose.... maybe to calculate the rise of British population, or wealth, or number of laboratories with aetheric power piped in, or miles of railway trackage within said counties... nice little readout dials or clicking digital readouts ... :-) Of course powered by a steam engine over at the side of the mechanized map. Now THAT would be cool.

But this is pretty, as-is.
