Since 2003 (Belasco Rogers) and 2007 (New), all journeys have been recorded with a GPS. They are the only people to have such a long record of every movement they make in this way. You can find an archive of GPS maps here
Belasco Rogers’s initial impulse was to watch himself learn about Berlin, the city he and New moved to in 2001. In 2007 New stated that she would do it for a year to observe how having a small daughter was effecting her movements. She has continued the daily practice to this day and does not now intend to stop.
The prints are sometimes made with a pen plotter or printed with archival inkjet inks on acid-free paper and mounted on Aluminium Dibond. As well as being exhibited in Japan, Brazil and Europe, they are in private collections in the UK and Germany.
