Can you guess what it is yet?

Yes, that's right. I'm building a QR code in Minecraft. Moreover, I'm
building the QR code for the server as a QR code... on the server.
Manually. (I could automate it but I like jumping up and down on
stacks of wool!)

I really don't care if it works (but it'll be cool if it does) - it's
mainly for a bad joke.

Fellow server denizens - it's exposed to the world at the moment, but
will be buried in an underground room once it's finished.

For the QR code curious, the code's attached as well...
