mLearn2007: QR Code stamps and shirts

I wore a different QR Code shirt each day of the conference, and also added a QR Code to each of the business cards I handed out using a self-inking stamp. I also had a manual stamp for demonstrating using different colours to create QR codes (with a green stamp pad)
