From Fridos Blog:
Wetterfroschi is a small desktop widget which always keeps you up-to-date about current weather conditions. Combined with an animated frog and further funny optical gimmicks, short information about weather data of selectable places are shown on a display panel by the program. Further Wetterfroschi also offers a detailed view which contains extensive specifications. Moreover, there is a weather forecast and some settings can be made, for instance if Wetterfroschi should be loaded when starting windows.
