Is that even possible? As far as i know there are certain keys for the QR code that should be done how it is. If that qr code is really working then that man is crazily talented. But I think that is really impossible to draw. Or maybe that person is using a printed one for the donation part.
We got the answer from hugeblack on how he did it.
It's impressive on how he's doing that with the perfectness of putting that QR code on his precious mural. This is what real talent is, this guy deserves to be donated.
Creativity really works but not all people are artistic enough to think of something that can capture the views of other people. I know there are other ways to do it but it would take guts and talent to do so.
It would take an amazing idea on how he'll get the attention of many.
