Sure. But mostly that is just an artifact of my attempt at ASCII
representation (it's about like postal bar codes). I think I could
recognize familiar patterns in most (but not all) of the samples pointed
out.

How about including the following in the document:

  The demo will evalulate whether an exposed bar code presents a
  danger of compromising anonymity.

I certainly do not think the matter is intractable. It's just a
question of whether we might need to include some kind of flap of paper
and/or deliberate obfuscation of the positions of vote choices. Neither
of those things is inordinately difficult, and quite possibly both are
unnecessary. I'm just not sure at this point.
