A GCI student wrote an user interface for a Weather application:

http://github.com/georgewhite5/HaikuWeather

Now this needs to fetch actual weather data from Internet. It should use one of the existing APIs and services for this, either using native APIs (BHttpRequest, BJSONParser) or a ported library.

* Add network support to the application,

* Make it fetch data for the configured city (and save the configuration)

* Make it update with a configurable delay

Inspiration may be taken from this older prototype: https://github.com/aldeck/weather (system APIs used there are outdated, however).
