Lichtenberg Lightning Frame
The Lichtenberg Lightning Frame is a fusion of industrial art, scientific experimentation, and visual effects. The frame measures 12 inches on each side. It is 1/2 inch thick solid aluminum with a bead-blasted front for a dull, textured finish. Two eyelets are threaded into the top of the frame for optional hanging with a chain.
The middle portion is a 1/2 inch thick acrylic block obtained from a now-defunct government laboratory. The pattern inside the block, which appears as a lightning strike frozen in time, was created by a process known as "dielectric breakdown" in which a material is charged with electrons (by a Van de Graaf electron accelerator) and then discharged to ground through a sharp metal point. Such formations were generated artifically for the first time by Georg Christoph Lichtenberg in the eighteenth century.
The block is illuminated by a multi-colored LED. The control circuitry, inserted into a hollow section routed in the back of the frame, is powered by a Microchip PIC12C508 and cycles through each of the seven colors at one minute intervals.
