Video popped up in my YT feed this morning about people dying from preforming Fractal Wood Burning Projects they found on the internet
Says ~30 dead in the US alone :O
So.. yeah
Like I always say, Don't fear electricity, respect it.
The most deadly project on the Internet

One of the problems of being 83 years old and having had twice that many "adventures," is that I usually have an incident related to other peoples' incidents.
I remember describing my experiments on APS with a 10kV oil burner ignition transformerwhen I was a teener:
"Wood, especially live wood, is not a non-conductor at those high voltages. I had occasion once to watch a 10KV (14,000 peak Voltage)) oil burner ignition transformer start to burn a carbonized trace from a connection to its HV terminal through the seasoned wood bench top toward ground. I shut it off right quick."

That carbonized trace looked exactly like the "fractal" traces in OP's article.
I didn't mention it in that particular post, but I did get an "educational" shock by touching the trace as it formed on my workbench while touching the transformer body.
I experimented a lot with that transformer, especially for rigging it up for spark photography.
Remember, a "10,000 Volts" rating (or whatever output voltage rating) means a peak voltage 1.414 times that amount. With a 10kV oil burner ignition transformer, that means peak voltage is actually 14,140 volts.

Never observed fractal wood burning myself, but in my younger days I did mess around a bit with a 9KV neon sign transformer. Just did the usual stuff, initially building something simple (a Jacob's Ladder) and ultimately making a good-sized Tesla coil.
Nobody died or was injured - even as a kid, I knew what I was doing well enough not to zap myself.
