I didn't realize that this was a common practice in Romania, too. :) I always got the impression (as a child) that it was a secret type of practice because anytime I asked about it, I was shewed away (not old enough) so I didn't learn the symbols but I thought it was fascinating and wanted to know more about it. I wonder if it is still being practiced or a dying art. I'm curious now.
I did look up Allen Williams' work - he is an amazing artist - content is a little too disturbing to me though ;) But I can certainly respect his skill.
