   * There exist image/audio patterns and [[https://​en.wikipedia.org/​wiki/​Denn%C5%8D_Senshi_Porygon#​Strobe_lights|video sequences]] that trigger seizures in some people. Take such sequence, show it to someone while recording EEG and measure how much "​unusual"​ brain activity it has generated - voilà, you now have an utility function (video) → (how good it is at causing seizures). Now use some kind of evolutionary algorithm/​optimizer/​hill-climbing to maximize this function. You might find a real-world [[https://​en.wikipedia.org/​wiki/​BLIT_(short_story)|BLIT]]! (yes, I know that optimizing a costly black-box function across video sequences is hard, but hey, the AI field solved similar hard optimizations in the last few years)   * There exist image/audio patterns and [[https://​en.wikipedia.org/​wiki/​Denn%C5%8D_Senshi_Porygon#​Strobe_lights|video sequences]] that trigger seizures in some people.
