See those photos, there, from yesterday. I see a series of parallel lines, along the X and Y axes, giving the illusion of a Z. Put something where the lines are wider, it looks closer, and where they narrow, farther away.

Follow the lines, follow the rules.

What if I stood outside of these lines? Would it skew your perspective? Can there be more than one horizon? What if I stood without the convergence, at its very end? What if I withstood it? Could you still see me? Would I disappear?
