In restless dreams I walked alone
Narrow streets of cobblestone
Beneath the halo of a streetlamp
I turned my collar to the cold and damp
When my eyes were stabbed by the flash of a neon light
That split the night
And touched the sound of silence
It is fun to revisit memories this way, a digital stamp in my weather passport, where everything can be contained in a forecast and Stockholm sits between Vilnius and London by sheer chance. It has also been a way to feel close to people I love while traveling, to know whether it is raining where they are.
As with most technology, this is artistry by committee. There is no Thomas Cole waiting in the wings. But someone has to animate the stars, to decide when to streak one across the screen–to play god in our pockets.
The contents of the city's images which are referable to physical forms can conveniently be classified into five types of elements: paths, edges, districts, nodes, and landmarks.
Paths are the channels along which the observer customarily, occasionally, or potentially moved.
Edges are the linear elements not used or considered as paths by the observer. They are the boundaries.
Districts are the medium-to-large sections of the city, conceived of as having two-dimensional extent.
Nodes are points, the strategic spots in a city into which an observer can enter, and which are the intensive foci to and from which they are traveling.
Landmarks are another type of point-reference, but in this case the observer does not enter within them, they are external. They are usually a rather simply defined physical object: building, sign, store, or mountain.
