To celebrate the creation of the QR Clock, a QR jigsaw puzzle has been created with the hard base64 hash backup of the full hashlink to the early September 2021 QR Clock version. This is the key to that puzzle. The jigsaw pieces are free the key costs to own but is free to look at to use.
Scan all the QRs in order (top:l2r, middle:l2r, bottom:l2r) and paste into an addresses bar in 1st scanned to last scanned. Go to the hashlink address you built and see the first free QR Clock version.
To view the most recent version check 3dd.in/QRclock and save the hashlink incase the short link fails.
