The picture for the day is a QR code (a two dimensional bar-code), which a friend introduced me to during the week. I'd seen these codes in many places but had naively thought they were just pretty patterns. Silly me. Little did I know that they actually contain useful information. Anyhow, this is a useful post on QR codes and tells you how to read and create them. Happy decoding :-)
