fractal wood burning

$fractal wood burning by Lara Sobel.$

Some photos from my initial trials of wood + saline + high voltage supply + variac. I have started making art pieces from this process. More info on larasobel. com.

Oh I really want to do this now. What a fantastic technique.

any chance of getting an instructable on what your setup was? Voltage levels, prep, etc?

Very cool, I think I will try it.

Looks like there's interest here! I will see what I can do in the next couple weeks and reply here with links to a more informative instructable, flickr set or video.

@snarkhunt &
@AEther

There's a 4hv thread thread on this I started not but three days ago! It has a couple of setup suggestions & some discussion on photographing it. You should both drop by & say hello.

This photo is really nice! That arc is precious!

Inspiring and good job. I´m also waiting for some updates... or maybe I try this my self.

Okay, So watching the video, what does the voltage actually do? Or is it just the laser itself burning the wood? Watch the video and you'll see the laser.

@erynthegrey, I´m afraid that there is no laser involved in this, what looks like one is the current burning the wood.

Pretty cool. Based on just the pic my guess would be that this piece of wood is either Luann or Mahogany (Honduran)

Very cool. Anxiously awaiting further instructions on how to do this!

This is beautiful and I love the idea but the patterns are not, in fact, fractal.

they are a little fractish. From the wikipedia article you cite:
* It has a fine structure at arbitrarily small scales. - yup
* It is too irregular to be easily described in traditional Euclidean geometric language.dunno, but I suspect yup
* It is self-similar (at least approximately or stochastically).yup
* It has a Hausdorff dimension which is greater than its topological dimension (although this requirement is not met by space-filling curves such as the Hilbert curve). erm, I dunno
* It has a simple and recursive definition. yup

myowncompass says:

Not to be completely tedious but "arbitrarily small", "self-similar", and "recursive definition" have precise mathematical definitions not met here (as far as I'm aware). Again, I love the idea and I can see the similarity to a fractal shape. I'm just making the point. I think fractish is a good description. :)

I am known to be tedious throughout the land, so here goes:

The arbitrary small limit for these Lichtenberg figures is the arbitrary limit of electrons. As far as a fractal can be expressed in reality, this is arbitrarily small.

In a uniform medium the branches are self-similarish.

I think it's as close as you could find in reality - because we have these messy huge limits at the level of atoms.

Now that I've been tedious, I'd like to share the related links about these figures. If you are as tedious as I am, you might enjoy this and it will save you some googling: delicious.com/snarkhunt/lichtenberg

Thanks for the links, snarkhunt. Those enjoying the debate of what exactly these are, may find this Flickr group very interesting: www.flickr.com/groups/emergence/
