Drawing on protocol

drawing-on-protocol

Drawing on protocol is a drawing constructed indirectly by its viewers, from the following rules:

  1. The IP address of each visitor to this page is recorded in the site logs
  2. The latitude and longitude of each visitor shall be estimated using a public IP look up service
  3. The route from one visitor to the next in sequence shall be found using a public mapping service
  4. If the route cannot be calculated from visitor i to visitor i+1, the route shall be attempted to visitor i+2, i+3, … i+n until one can be found
  5. When a route has been found, it will be drawn freehand on the paper, the page representing a coordinate space of 360°x180°, with 0,0 at the centre
  6. The hits will be recorded from the date of the first upload of this page, 20th June 2009
  7. Repeat hits from the same IP address will be ignored
  8. The drawing will be judged complete on whim, and no more lines shall be added

UPDATE 25th August: more lines added, and deemed complete. Most new entries were repeatedly in the same places – Seattle, California, or different network hubs in the UK and Europe.

UPDATE 2: best to do this sort of thing automatically, rather than with pencil and paper.
