Weather data from many world locations is gathered from a server and accommodated in a dynamic visual representation. The dynamics of the wind at specific world locations exercises influence over a mass of floating particles in a virtual parallel world. Particles in turn influence the production of complex sounds. In effect, a rewarding aesthetic experience results from the appreciation of the intricate interplay of two complex dynamical systems; one of natural origin (the earth), the other of cultural design (the program).
Previous research exploring the Earth as a global source of information includes the translation of the Kp indices reflecting the Earth’s magnetic field into musical pitches and compressing thousands of data items into a few minutes of musical time. Sonification / Listening Up is a more recent MIT project aiming the sonification of the interplay of sun winds with the Earth's atmosphere, a continuous interaction that takes place some 60 miles above ground level.
The conviction that rewarding aesthetic experiences may result from the perception of multifaceted behavior in a given complex system underpins the present project.
More precisely, the global systems output here emerges from the confrontation of two complex dynamical systems: (1) the complex stretch of non-linear forces instructing the development of wind across the surface of the Earth, and (2) the largely unpredictable (though coherent) behavior in a sounding network of digital audio processing units. So, the earth is considered a found system while the sound producing system is a deliberately constructed system; the net result is collaborative effort involving a natural and a cultural system.
