Virtual suturing practice
Publications

  I remember writing some of these
in pencil,
and mailing hard copy to a collaborator.
  I remember when to put computer graphics into a book, I had to beg a favour from one of the few places that did it, eight time zones away.
  I remember the term nominal aphasia.
  But I cannot remember people's names.
