Balloon Earth – 3D city maps with real time weather
Balloon.earth is a Chrome Experiment that uses a combination of real-time weather data and 3D map renderings. The authors call it digital ballooning. They use Google Maps, Open Weather Map and NASA for their data sources.
You can use the mouse to pan and zoom around and if you wish to explore another city you can do so by clicking the tiny globe in the bottom right corner. The only downside perhaps is that the city-choosing process is random, you can not pick a city to go to.
You can take a look at this experiment here.
