 Contrary to the composition of Modest Mussorgski’s "​Pictures at an exhibition"​ the installation takes up its sound directly from the picture itself. The "​Picture Discs" are semi-transparent miniatures based on dysfunctional DVD s. The picture itself is created by abstract chemical-magnetic processes that involve liquid iron. A Raspberry Pi Camera with a macro lens films the abstract picture, which is magnified and projected to make it visible. Contrary to the composition of Modest Mussorgski’s "​Pictures at an exhibition"​ the installation takes up its sound directly from the picture itself.

 Thus destroyed digital data are transformed into an organic form that can be seen as a renaturation of the bigdata: Layers of earthy colors resemble tectonic plates whose structures are made audible by a laser that scans the rotating picture. The laser emits rough seismic waves and by doing so modulates a light-sensitive transistor. As the signal is amplified and modulated by an electric circuit based on the legendary 808 drum machine the tremor of deep frequencies that usually lie beyond humans’ ability to hear is transmuted into the rumbling sound of a rich bass. Thus destroyed digital data are transformed into an organic form that can be seen as a renaturation of the bigdata: Layers of earthy colors resemble tectonic plates whose structures are made audible by a laser that scans the rotating picture.
