The KML file contains 43,000 lines connecting every ZIP code in the country, TimeStamped in ascending numerical order.
Just a slight warning: This is a very large and detailed time animation. It runs smoothly on my 3-year old PC (the little GIF above is from a real time capture), but may not work on some computers.

Viewing the File
- Hit the play button in the Time Control, top right of the screen, or just drag the slider left or right.
- Expand the time span to increase the number of ZIP Codes displayed at any time.
- Deselect folders in the left sidepanel to alter the scope of the animation.
- Change the visualization to a cumulative animation by selecting clamp beginning of time window in the time option dialog – accessed through the white clock icon to the left of the time slider.
- The numbers shown under the Time Control are 5-digit ZIP codes without the leading zeros.
- States are different Colours. No significance in the choice of colour – it’s just for contrast with one another and the terrain.
- White lines indicate the sequence jumping a State boundary.
