The world was given an extraordinary view of itself last May as part of a collaboration between NASA, the USGS, TIME and Google.
Anyone can now watch a 1984 to 2012 time lapse from space of anywhere on Earth. Despite its initial splash in a number of tech blogs, the existence of the unique Google search still finds new fans months later.
The core images come from joint USGS, NASA project called Landsat, which has been collecting satellite images since the 1970s.
Google reports that that it went through 2.1 million images - 909 terabytes of data - to find ones with the highest image quality, and without cloud cover.
Using it is as simple as typing in the city for which you wish to see a time lapse.
The effort can be intoxicating, and time-consuming.
In the core Portland area, watch skyscrapers and massive retail centers erupt, watch suburban subdivisions emerge out of trees and farms. Scroll up to Clark County, down to the Willamette Valley or across to the Coast and Eastern Oregon.
The growth is equally dramatic in the Puget Sound region, especially the Seattle suburbs.
