100 years ago the Futurist Luigi Russolo introduced the Intonarumori to the public and Bauhaus Artist Laszlo Moholy-Nagy created his "Light-Space-Modulator". The first apparatus generates noise and the second one generates moving light/shade patterns.

Both aspects inspired the installation "Bilder einer Ausstellung". A laboratory like setup functions as the generator of both abstract projections and corresponding noise. Contrary to the composition of Modest P. Mussorgsky "Pictures at an Exhibition" the sound is not only related to the pictures but directly taken from the picture itself.

The "Picture Disc" is a transparent miniature picture based on chemical-magnetic experiments with liquid iron. A laser scans the rotating picture optically. After transforming the light beam in an electric signal it is modulated by an electric circuit based on an old analog 808 drum machine. Additionally a camera magnifies the images of the disc and projects them in order to frame the installation as a whole.
