About Earth Clock
Earth Clock is a digital clock assembled from views of Earth from above that resemble numbers. Every minute, five windows fly to five places on the planet: two for the hour, a colon, and two for the minutes. Each place, seen from directly overhead at the right altitude and heading, happens to look like a digit.
The clock has been running since 2011. It was built by CW&T (Che-Wei Wang and Taylor Levy) at FABRICA, with support from tamasha.
The places
There are over a thousand places in the clock so far, and many of them were found by visitors. Anyone can scan the globe for a shape that reads as a digit and submit it. Submissions are reviewed before they appear in the clock. You can contribute a place yourself.
On the clock, drag and zoom inside any window to explore the area around that digit. The address of each place appears beneath it.
Help us put this on a giant screen
We would love to install Earth Clock at an airport terminal, on the biggest screen we can find. A clock made of the Earth belongs where people are about to cross it.
If you know an airport, a terminal operator, an art program, or a screen that might be a fit, we would appreciate any leads. hello@cwandt.com
