Using electricity to make a portrait of
Inventor, Engineer (c. 1856–1943)
Serbian-American inventor Nikola Tesla developed the alternating-current electrical system that's widely used today, and discovered the rotating magnetic field (the basis of most AC machinery). So it is only fitting that electricity be used to paint his portrait. (I'm sorry, I don't know the name of the artist.)
