[emeqfxrq] QR code clock

5 QR codes and a blank space arranged in a 2x3 array.  Each code encodes Unix time as a decimal number.  Each second, a new code appears at the blank space, and the oldest code turns blank.  Critically, the codes do not move, keeping them easy to scan.  Previously.

We can also imagine a human-readable version, with date and times formatted as text.

Not sure what these would be useful for.
