Video of Willard Wigan's work. Wigan makes exceptionally tiny sculptures that fit on pin-heads or within eyes of needles. He once lost a sculpture of Alice in Wonderland:
I think I inhaled her.
Some of the parts of his sculptures are no bigger than human blood cells and to steady his hands, he works in between the beats of his heart.
The stillness of it is very important -- you have to control the whole nervous system, you have to work between the heartbeat -- the pulse of your finger can destroy the work.
