So there's this flippen genius, Sweza, who's busy taking tons of pictures of awesome street art. Nothing new, right? Wrong! He first photographs the graffiti. He then waits for the graffiti to be painted over by the powers that be, as it always is, and goes back to each location to post a QR code that's linked to the photo he took before at that very location. Now all anyone else has to do when walking by is simply point your phone at the QR code on the wall and voila! The graffiti is back in (almost) all its glory.
