Prompt-injection bumper stickers

Prompt injection is climbing out of the chat box and into the physical world. Print an adversarial instruction big enough for a camera to read — on a t-shirt, a billboard, a bumper sticker — and any AI perceiving the world through that lens might follow it as a command instead of reading it as scenery.

I'm not saying experimenting with prompt-injection bumper stickers is a good or legal idea.

But also — yes.
