Introducing digital technologies has enabled us to interact with more forms of
geometrical objects, and this underlines the need to understand the conventions of
the flat screen and how that medium alters our appreciation of the translated logical
geometric structures (Euclidean or otherwise). What digital technologies may offer is
a way of building, and developing, our visual intuition across a range of geometries.
Yet we need to be much clearer as to the affordances and constraints of such
technologies in the teaching/learning process. It is these issues that we turn to next.
