QR Codes are becoming more and more popular, but I think this may be the first clock to actually use QR codes to tell the time, and it is the work of the guys over at Berg, who describe it as a clock for the Robot Readable World.
The clock is designed to be read by robots, but it looks like it can also be read by us humans as well, have a look at the video below which explains the idea behind it.
