QR codes [1] have been around for quite some time and I've been meaning to play around with them, but lacked the software to generate them. Just recently though, I came across QArt Coder [2], a web based application to generate QR codes.
I slapped in http://boston.conman.org/ [3] and the result was amazing:
[QR code of http://boston.conman.org/] [4]
Who'd have thought the QR code for my own site would look that way?
