Psychogeography via Post Boxes

Post box score
  1. Move randomly until you encounter a post box. A map of boxes in central Huddersfield is available.
  2. Record the first letter of its Royal cipher (E,G,V). Record O for the rare cases of no cipher.

  3. On its collection plate will be a number (usually at the bottom, following half a postcode); collect this number and divide by 4. (In the image, the number is 74, we "next right".)
  4. Deal with cul de sacs,loops and inpenetrable obstacles as you see fit.
  5. ... until you've had enough.
The excursion's gene sequence is the E/G/V/O sequence you have recorded.
Collect some of these and seek genetic similarities between different starting points.
