This is really cool. I worked on something similar during a hack day while I was still at Twitter. https://github.com/jkubicek/Switters https://github.com/jkubicek/Switters My project used QR codes attached to a tweet as images to encode the message. It's still got a long way to go before it's at all user friendly, but I had fun building it.
