> My visual representation is definitely 3 dimensional and I am not sure what you mean by abandoning it? I mean, code is statement blocks and controll flow elements. It is data and connections between them at execution. I can imagine, not being visual gives you much more focus and fewer distractions on the mental map, but is it really different?

An earlier commenter described it like a directed graph. I think that's a pretty good way to describe it. As for whether it is different, I don't know how others think. But one thing I do know is that this is how my mind worked for non-analytical thought before I went blind and still does. I'm just more aware of it now that I don't visualize as much. I only really visualize things these days as a way to communicate ideas with sighted engineers.
