  Whereas for a substantial part, Finite Geometry during the past 50 years has
focussed on geometries over finite fields, geometries over finite rings that
are not division rings have got less attention. Nevertheless, several important
classes of finite rings give rise to interesting geometries. In this paper we
bring together some results, scattered over the literature, concerning finite
rings and plane projective geometry over such rings. It doesn't contain new
material, but by collecting stuff in one place, we hope to stimulate further
research in this area for at least another 50 years of Finite Geometry.
