I feel like if I can get it working reliably I might have fun setting up a website to make them for $1 each or something. Right now though the process I have is to make 16 at a time with various settings and seeds and then run my phone over them all and see which ones the camera can read as QR codes. Finding one that is both nice to look at and reads reliably is rare.
