It is a pretty impressive demonstration of the error correction built into QR codes.

That's so great we can plaster logos in the center of it without any reasonable considerations and it would still work, so that's now abused by many apps and services. No, they weren't designed to do that, it's just a random obstacle, like a dead bug, that doesn't obscure the reading too much. Trully impressive.

While not strictly a QR code, I always liked that the Dolby Digital data between perforations on a film strip had a tiny Dolby logo at the centre.
