I'm sure that over the years they have been part of the design inspiration for sure. In fact I think the idea that the "top" armor plate it somewhere behind the head, overlapping to both sides is something the Nids also do these days, might be spawned by ghibli.
Meanwhile I am concluding I can spend an entire evening on something a few cm. to a side when working on a 6mm building.

Ah well, I guess a walled farm is quite a large building.
