Captured Lightening - Bert Hickman: Lichtenberg figures (fundamental to today's laser printers) are the patterns resulting from high voltage electrical discharge ( here 2.2 million volts) through a material, in this case acrylic. This remarkable sculpture is illuminated by white LEDs and mounted in a rosewood base.
34 touch sensitive salt crystals spread over a world map highlighting the biggest salt mines. According to the amount of salt mined in these regions, millions of salt particles are emitted over the world map, slide down the mountain ridges, then diffuse and flow with the main sea currents. When a crystal is touched, it starts to glow. Grains of salt pour over the table and merge into an information window
Lichtenberg figures (Lichtenberg-Figuren, or "Lichtenberg Dust Figures") are branching electric discharges tree-like or fern-like patterns that are created by high voltage discharges along the surface, or inside, electrical insulators.
