MU - 'Weather or Not' group exhibition

tele-present wind by David Bowen consists of a series of 42 x/y tilting mechanical devices connected to thin dried plant stalks installed in a gallery and a dried plant stalk connected to an accelerometer installed outdoors. When the wind blows it causes the stalk outside to sway. The accelerometer detects this movement transmitting the motion to the grouping of devices in the gallery. Therefore the stalks in the gallery space move in real-time and in unison based on the movement of the wind outside

Listen to the sound of... the sun

Aernoudt Jacobs presents Heliophone, an installation which turns sunlight into sound. In order to create this installation, Jacobs researched the ‘photoacoustic principle’ as discovered by Alexander Graham Bell at the end of the 19th century. The basic principle of Heliophone is simple: energy from the sun is transformed into sound without electronic amplification. In the design, however, Jacobs combines an impressive array of traditional and cutting-edge technologies. The installation follows the trajectory of the sun, catching the sunlight and focusing it, via a parabol- ic lens, onto one point. There, a rotating disk chops the light up into small fragments. A photo-acoustic cell further transforms the light fragments into sound, made audible by a large horn.
With Heliophone, Jacobs created a sound piece for the sun; the tonality of the installation constantly changing with the intensity of light. In this way, the notion of ‘environmental sounds’ gains an entirely different connotation.
