- Spark generator, electrodes
- dimensions variable
Sparks discharge on a wall and appear in the form of short light flashes. The flashes light up and are accompanied by a very short impulse sound, which is perceived earlier by the visitors than the light flashes. In contrast to the fixed positioning of the 18 electrodes, the sequence of the sparks is andomly defined. Thus the resulting image the sparks draw is constantly changing; the permanent interplay of light and sound cause a oscillating effect.
