Virtual geoglyphs! Sort of like a 21st Century techno-version of early 15th and 16th century maps that drew out animals, crosses, heraldic devices, etc. in geographic landforms. I’m also reminded of the characters in Paul Auster’s City Of Glass who draw out a sentence in their movements around New York. Suspicious folks will probably notice that it’s a particularly British phenomenon.
