Needle work by @sadgaydontcry
Tessera generates the file; the artist puts it on the skin. Those are two entirely different disciplines, and the second one is harder. A QR code is unusually unforgiving as tattoo subject matter: no forgiving curves, no organic asymmetry to hide a slip, no room for interpretation. Every module has to land in the correct 1.7 mm grid cell or the whole thing degrades at once. The finder patterns have to be clean. The quiet zone has to be respected. The modules have to be dark enough to hold contrast for decades.
This tattoo was done by @sadgaydontcry on Instagram. Every credit for the physical mark belongs to them. The generator is the easy half of this collaboration; the hard half is above.
If you're planning your own permanent-mark tattoo and want the same level of care applied to the needle side, that's where to look.
