'abstract' wood burning.

Not sure if this should be posted here, Outdoors or Square Pegs, but it's art related so I'll ask here.

I once saw a how-to video, I am 90% sure is was on this site. but there is a chance it wasn't. I would like help finding it again.
From what I remember, the person showing off had: a car battery, a long needle,  plank of wood and some chemical.

the process I remember was (but may not be 100% accurate):
1. (s)he painted on a layer of chemical (or acids) on the wood
2. stabbed the needle on the wood
3. connected the battery to the needle
4. turned the battery on.

it then made some elegant, fancy patterns, like a bare tree, or a lightning bolt. lots of 'branches' and paths were burned into the wood (without manual intervention. it was 'natral'). like a chemical reaction.

if anyone has the name of this technique, or a video/instructable/guide, I would really appreciate a link.

Thank!

EDIT: solution found: it's called "Fractal Woodburning" (go on youtube for some videos). I should have known, I love fractials!
you need:
saline
wood
needles
and a high-voltage power source.
and patience.

There is Kirlian photography or look up the Alfred Smith pyrography technique and see if that helps.

Not quite. that looks manually made. the process I saw the person simply put the needle in the wood with chemicals on it, then the electricity from the battery burned in (slowly) the design. following the wood and/or chemical patterns. results kindof looked like a 'sloppy' lsystem (similar to this) http://dreamsyntax.org/opencall/ideas/l-system.jpg

Lichtenberg patterns with another process?

hmm, yeah. that seems pretty close to some of the designs I remember, not as uniform as an L-System. thanks.

There must have been some other connection to complete the circuit, in addition to the needle). Maybe a strip of metal around the edge.

Are you sure it was burned into the wood? Could it not have been a colour-change in the chemicals, subsequently staining the wood below it?

that's possible. I just remember the fancy patterns it made with minimal human interaction. maybe the chemicals + electricity stained the wood, or burned it. but I remember seeing smoke so I assumed it was burning (could have been evaporating chemicals after the electricity went by it, I guess..).

not sure on the metal. could have had some. It was a few months ago that I saw this and probably don't remember everything involved.
