the tip of an accupuncture needle
"When the measurment of man is is nothing more than the apex of an accupunture needle...Our collective and individual perception must change."
On a related note to this ancient art form...
---In successful pinhole photography... I have read that the accupunture needle is an excellent tool in achieving the precision hole. I.e. if you happen to know the "good doctor."
To anyone interested in pinhole imagery... I would suggest for further reading... the book by Eric Renner. An excellent reference work.
