Visualization

We've been doing quite a lot of visualization work lately (read: 3ds Max), which is good as a bill-paying enterprise. What strikes me as odd, however, is the fact that visualization as a skill is not very widespread. Orthogonal drawings are a kind of code, best interpreted by people in the know, but opaque to everyone else. So why not draw in a 3d world, or even 4d? After all, we interpret reality as a 4d world.
