  Finite fields form an important chapter in abstract algebra, and mathematics
in general. We aim to provide a geometric and intuitive model for finite
fields, involving algebraic numbers, in order to make them accessible and
interesting to a much larger audience.
  Such lattice models of finite fields provide a good basis for later
developing the theory in a more concrete way, including Frobenius elements, all
the way to Artin reciprocity law.
  Examples are provided, intended for an undergraduate audience in the first
place.
