Todd Johnson produces "Shockfossils", Lichtenberg figures, that are carved in acrylic by the immense power of a rented electron accelerator. After charching the acrylic it passes the 5 million volt electron accelerator, then the acrylic needs to be hit with a hard object. Immediately after the stroke a discharge happen and builds tiny structures of the electrons traveling through acrylic. He can even cover parts with lead masks to control where the effect happens. The Shockfossils are then mounted on a wooden holder and lit by LED's, a commercial product...
This is just awesome, I'd like to see this process live.
