Æther uses electricity to draw patterns in wood, with beautiful results –

did some experiments last night: wood + saline + high voltage supply + variac = fractal burn patterns. tried different kinds of wood with various effects. unfortunately my recollection of which types of wood are displayed are spotty. will update later. stay tuned for photos of my fractal wood burning coat rack.

Surely a technique other wood artists will be very interested in. – fractal wood burning on Flickr
