The interactive installation meteo flux – eine Symphonie der Atmosphäre [a symphony of atmosphere] responds to changing weather conditions with sound, vibration, and light. At its centre stands a tree sculpture: as a vibrating sound body, it relates the current temperature to the average of the past 40 years, making climatic deviations audible, tangible, and visible. It is surrounded by four living trees that themselves become sound sculptures, each with its own identity. Rain, wind, or sunshine each generate a distinct composition. The audio material is based on field recordings from Karlsruhe and its surroundings.
On the hour, every hour, the composition briefly shifts for a few minutes into a dystopian soundscape: natural sounds increasingly dissolve into electronic structures before the system stabilises again.
Visitors actively shape the sound space: by approaching individual trees, they activate characteristic sounds that wander between the trees and then return. In this interplay of people, nature, and technology, a continuously evolving soundscape emerges, in which weather becomes directly experienceable as a living ecosystem.
Further depth is offered by the nearby Teehäuschen, the artistic documentation of the project: the spatial installation Climate Forest visualises long-term climate change in Baden-Württemberg, while QR codes provide access to scientific background as well as an interactive Sound Map Karlsruhe.
