Hold on, though, if it's a model of Bourton-on-the-Water, and Bourton-on-the-Water has a model village, shouldn't there be a model village in the model village?
There is indeed.
Just a moment. If the model village contains a model village, shouldn't there be a model village in the model village's model village?
Yes and there is.
I think you probably can guess where this is going...
The resolution of the village (and my phone) runs out at depth five.
So this is a model village in a model village in a model village in a model village in a model village in the village they're modelling. It's recursive.
There's a greater interesection between model-makers and programmers than I had realised.
