You can use adversarial neural networks to make a special picture that looks like noise or junk, but a certain neural network will recognize e.g. a dog in it. You basically train the ANN to make something that the other NN classifies as dog, but humans don't.

I often wonder if you could do that with humans. I don't think you can crash a human brain a la Snow Crash or Basilisk, but I think it is plausible to craft an abstract picture that creates fear, arousal, or some other "primitive" response.
