On the web I have not come across anything worthwhile.Does anyone have such a picture? So we can see the hairs emitting?
Personally, for 10 years I had long hair down to my back, and I remember having many deep experiences during this "hairy" time, and also at 40 years old with short hair I had other deep experiences at other levels, that most of us can have in a life of research.
And so I think that like any antenna or other tool, you have to be aware of it and know how to plug it in and make it work for yourself and then for others, knowing that there will always be interference, and being able to rely on another tool, or another person.
A little souvenir from that time!
