Love it or hate it, artificial intelligence is here to stay — so we might as well have some fun with it. A few months ago, engineers made ControlNet, an addon to Stable Diffusion, one of the most advanced image generation models. ControlNet made it so the AI could draw two prompts at the same time. One of the earliest ideas for how to use this was to make it easier to put QR codes into AI-generated images of other things — so that if you were an Italian restaurant, maybe you could make a QR code picture that looked like a plate of spaghetti, and would still scan.

But fans and enthusiasts of AI art quickly found other uses for the new technology — including making a new kind of optical illusion. They learned how to put Hidden Words In AI Art. If any of these aren't clear to you, try stepping back from your screen. It may allow you to see it all in a new light. It still takes skill from the human to prompt the AI so it can produce the hidden word in a way that's fun rather than too obvious or too difficult. You can try it out yourself using the generator at Glif, an AI art site.
