I think the Lichtenberg Fractals burns are interesting and beautiful, but as Tom said I wou't be trying it anytime soon -- like NEVER -- when I was in the Navy I cross joined a repererator machine (a machine that punches telex tapes) leads and sent about 300 volts through my elbows... fortunately the current was relatively low, but when I got up off the desk that sat about 6 feet away from where I was making the re-perf change, I had knocked out every circuit in the communication room, including the lights, and somebody hit me in the elbows with a baseball bat. The fact that the circuits blew out likely saved my life. There was a place where the re-perf maching hit the base case which was a little over 1/8" thick metal and blew a quarter sized hole in the case. I don't mess with electricity much other than changing a light bulb.
