This is a QR code generator built with just redstone. You can type 17 characters using a QWERTY button keyboard and the machine converts it to a massive scannable QR code. Since it takes about 12 minutes to generate the QR code, this map features a museum with fun facts for you to read while the machine is doing the stuff.
