kinda on topic, met a guy last weekend at the gunshow
he makes wood planks and cutting boards using some fractal engraving , (may have that wrong)
he basically has a rig that shoot electricity (like lightning) thru a piece of wood then fills the voids and coats it in a clear coat,
only he slipped and touched something he should not have and fractaled himself, ground on his foot, and then shot thru his head,
he showed me a pic of the hole in his head (about the size of a 22) where the current exited, (he guessed 4000 volts, but no way to know)
it messed him up, had to do rehab etc etc
