While looking at a grayed-out military base on Google Maps sent to me by a friend and visible above in the lower right-hand corner, I found a link to the above map. It appears that pizza delivery driver Will Dockery and his fellow employees have documented their deliveries from October 20, 2008 until the most recent update on September 8, 2009.
I love the overlapping histories and trajectories; Dockery’s deliveries bounded by the forbidden zone of the military base. What if every cell phones enabled a simple tracking of a behavior, overlaid on a map? What if this kind of data were as ubiquitous as photography?
