I was thinking the other day about some sort of augmented reality thing , where a "graffiti" artist could put a simple qrcode somewhere on the streets, and without having the the graffiti artists public key or being in their web or trust (I don't know how any of this works by the way , I'm just letting my mind wander) , then all they see is a qrcode with jibberish, but if you have the right keys , then you can see the art plastered on the wall, or some secret information about the street or the people that live there.
