From earliest times people have created specific constructions that in some way give form to landscape; focal points if you will.
From cairns on hilltops to church towers, to carved horses on chalk downs....it's all in it's way 'public art'.
Personally I like the reference points they give us
and ones that catch the eye and one thinks, "Oh, that's good
", do double duty.
Andy Scott makes structures that really do 'fit', that really do have visual appeal for the majority. None of the straining to see just what the artist was on while under the creative process/well that didnae work, sort of thing.
