Hah, this is so cool! I just discovered the qrcode module in Python, which apparently comes preinstalled in Ubuntu (?) and allows you to generate ASCII terminal-printable QRs of any string you want.
Here's this website, for example:
█▀▀▀▀▀█ ▄█▀▄ ▀▀▀█▀▀ █▀▀▀▀▀█ █ ███ █ █ █▀▄ ▀ █▄ █▄ █ ███ █ █ ▀▀▀ █ █▄█ ███▄▀▀▀█ █ ▀▀▀ █ ▀▀▀▀▀▀▀ █▄▀▄▀▄▀▄▀ ▀▄▀ ▀▀▀▀▀▀▀ █▄▀▀██▀▄▄█▄▀▄ ▀█▄█▄█▄▄███▀▀ ▄ ▀▀▀▀█▀▀▀▀██▀ ▄ ▄ ▄▄ ▄█▄ ▄ ▀█▀▄▄ ▀ ▀▄▀▄█▄▄▄▀▀▄███▄▄▄▀▀ ▄ ▄█▀▄█ ▀ ▄ ▄ █▀█▀ ▄█▄█▄▀▀▀▄ ▄███▀▀▀█▄▀▄ ▀█▄▀ █ ▄▄▄▀█ ▄ █ █ ▀ ▀▀ ▄██▄ ▄ ▄▀█▄▄▄ ▀▀ ▀▄ ▀ ▀▀▀▀▀ ▄ ▀▄▄▄▄ █▄▀█▀▀▀█▄███ █▀▀▀▀▀█ ▄▄█▄▄█▀▀▄ ██ ▀ █▀▀ ▄ █ ███ █ █ ▀▀ ▀ ▄▀▄▄█▀▀▀▀▄█ ▀ █ ▀▀▀ █ ▀▀█▀▀ ▀▄ ▀█▄▀█▀██▀█ ▀▀▀▀▀▀▀ ▀ ▀ ▀ ▀ ▀▀▀▀▀
And it works, you can even scan it with your phone. Pretty cool!
And happy October too, btw!
