I have spent a lot of time lately working with two-dimensional representations of multidimensional states. No, I don’t mean anything arcane and mystical… or something that belongs in the realm of science fiction either. I’ve been working with pictures.

We tend to think of dimensions in spatial terms of height, length and depth. That is how we are first taught about the whole affair in school and why would we question it? We simply accept that we live in an apparently three-dimensional universe, and that an image, for instance, is only a two dimensional representation of a wider reality… a symbol, if you like. It has become widely accepted that ‘time’ makes a fourth dimension… the difference between how things were and how they are. Time travel has become such a popular idea through literature and entertainment that none of us boggle at the possibility… even while we accept it…
