This is another attempt to make a QR code to put on my artwork, this time with the code on top of my signature but with the signature full width, so I could make the code smaller. This was done in GIMP -- the layer with the signature actually occurs twice, once above the QR code in "Screen" blend mode to turn the black pixels purple, and one below it in "Normal" but with a decreased opacity, to turn the white pixels purple (but a lighter purple). I tweaked the opacity until the signature was visible without making the QR code unreadable by my phone. Again, the code is just the URL to my FA profile.

This time there are only 2x2 pixel squares, so it reduces the size of the QR code ugliness. I still don't know if I'm going to use this, though. Mostly I'm doing this just to be clever and prove that I can, but I'm not going to make my drawings ugly just to do that.
