“Unfold a street map of London, place a glass, rim down, anywhere on the map, and draw round its edge. Pick up the map, go out into the city, and walk the circle, keeping as close as you can to the curve. Record the experience as you go, in whatever medium you favor: film, photography, manuscript, tape... be alert to happenstance of metaphors, watch for visual rhymes, coincidences, family resemblances, the changing moods of the street, complete the circle, and the record ends…” (Robert MacFarlane – Psychogeography: A Beginner’s Guide)
