Hmmm... imagine you had a cybernetic eye that someone hacked.

At present, I'd imagine a hacked security camera or maybe even a hacked cell phone would be the current methods of choice for receiving the brightness-encoded signal.

Back in the days of CRTs, I heard some secure facilities had their monitors all enclosed in boxes with metal window screens, as they were worried about data leaks via EMI. That sounds annoying as heck to try and look through, all day.

Still less annoying than dealing with the theft I'd imagine.
