One of my favorite artists,
Dave Archer, uses a Tesla Coil for his work. He starts with a piece of glass, places a smear of isopopyl alcohol on it in key places and patterns and then hits it with the Tesla Coil. He then fills in the rest of the painting, starting with details and then filling in the background behind it (reverse painting). I am fortunate enough to own an original, albeit a very small one.
This is one artist who's work you definitely have to see in person to appreciate.
