I have 6 spaces. How would this solution work for that?

  Maybe: x xx xx x Worst-case would be going from far left to far right, which would take 3 presses.

  I've never actually used this before, but I've always envisioned arranging them in a cube, one on each face.

    The problem with a cube is that you will always end up with at least one upside-down screen.
