A few days ago I listened to an episode of one of my favorite podcasts, The Candid Frame, hosted by Ibarionex Perello  where he had the photographer Mick Victor as a guest. They talked about his project of photographing graffiti, tags and other decorations and markings on walls close enough to make them more abstracts, and therefore more "arty". I thought that sounded so utterly removed from the street photography that I often do that I just had to give it a go!
