The "Besserwetterkompass" is a compass which guides you to sunnier places. By connecting to the web it compares the weather at your location with the ones around you and guides you accordingly. It plays with the joy of the unknown and discovering your surroundings without a certain goal in mind.
It was developed within three weeks in a data visualisation workshop, guided by Benedikt Groß. The compass uses a micro controller to get data from the OpenWeatherMap API, computes it and displays the travel direction.
