Workshop Canadian Woodworks are decorating wooden furniture in the way you’d least expect – using electrical discharge. They have been burning Lichtenberg figures (branching tree-like patterns) on their products and they look absolutely mesmerizing. Lichtenberg figures are named after the German physicist Georg Christoph Lichtenberg, who originally discovered and studied them. The study of Lichtenberg figures along insulating surfaces and 3D electrical trees within insulating materials often provides engineers with valuable insights for improving the long-term reliability of high voltage equipment.
