DataCloud
DataCloud is a data visualisation system that displays the live weather conditions of major cities across the globe simultaneously. The climate information is gathered from airports all over the world and updated several times a day.

The weather conditions are mapped onto each
city's name: font size relates to visibility, colour
to temperature, and transparency to humidity.
The city names move with the speed and direction of their wind readings while their atmospheric ressure is applied as friction to the movement.

Each time DataCloud launches it loads an image from a different location worldwide.
The photographs have been submitted by users around the world.

Please note DataCloud can be processor intensive.
