Cool! I hand painted a QR code[0] in about .75x.75" onto a painting my father did for a friend and while working on it I spent about an hour or two implementing different codes of varying complexity in pencil to see how far I could go before it would get corrupted. It actually works[1] but it's on the wall in a music venue so unfortunately it takes a few extra seconds for some people's phones to adjust to the lower light.
