I noticed some strange lines in the background of Q's flag pic from https://8ch.net/patriotsfight/res/62.html#319
Looks like a long barcode after coloring it to solid black and white, but I can't get it to scan.
I got mine by inverting the image, and then boosting magenta a lot until finally turning it black and white.
I'm not getting a readable barcode though, could possibly be getting screwed up by the flags own border…
I've been doing some cleaning, and straightening out artifacts from the color conversions.
Now my problem is figuring out what kind of barcode it is, there are MANY types.
