Kevin Uhlir has been in contact. He’s built a lovely clock by using a Raspberry Pi. Built into the screen of an old monitor, the Pi retrieves data from Weather Underground and maps from Google Maps. He’s built several of the units, including some for friends and family. It looks lovely! He’s even extended it with amblight effects on some of the units. You can read more over on his blog or at Hackaday. Full instructions and the code can be found here.
