Nerd Picture
QR codes are all the rage in Japan and are showing up in other parts of the world. A QR code is like a hyperlink in the real world. You could attach this to a physical object and then use a QR code reader (aka cellphone with a camera ) a link to a website such as this. The code here is rather useless because it links back to here. Why have a picture to link to yourself? Because it’s cool!
You can create your own codes and get your own reader
