What makes this interesting and unique:

  Instead of scribbling on redundant pieces and relying on error correction to preserve the meaning, we can engineer the encoded values to create the picture in a code with no inherent errors

I’m blown away that there’s no comments on this submission!

This is a great write up that explains how they have generated QR code art by exploiting the format of QR code.

Kudos!

I wonder why companies don't just put their logos in the corners. Also long as the logo is dark enough to read as "black" (ie sufficiently saturated to not read as white) the position markers ought would allow for branding without sacrificing any of the informational redundancy in case of damage.

I wonder if this could be combined with smart dithering to further improve the visuals?
