Last month I profiled a project titled 'Energy technologies visualisation for the IEA'. Well, the Raureif folks have been busy and have just this week launched a stunning new data visualisation design in the form of a weather app for the iPhone called 'Partly Cloudy'.

Partly Cloudy’s visualisation shows a weather forecast in the form of a radial display like an analog clock. The weather is portrayed using color, rather than via lists of digits and icons which allows you to sense an entire day’s temperature patterns at-a-glance. Extra layers of detail are represented by a blue pattern from the centre indicating the forecasted rain fall and there is also a pattern for the expected wind strength.

You can modify the view to show options for 12 hour, 24 hour and 7 day views but the real beauty is the rotating slider as it reveals new details of the weather forecast coming up.

Partly Cloud is not the first venture in to the iPhone App market for Raureif's, they have also developed the Virtual Water project and the EcoChallenge app.
