When I’m bored of watching the people on the street – or there’s no one around – I like to stare at walls (only if there’s something interesting on them, mind). And I take a photograph, which some of you might know because of my other street art posts. Most of these were taken around Covent Garden. A few were snapped when I was visiting a friend and there was a lull in the conversation. I watched the guy paste the squiggly sticker on the bricks on Long Acre. Can anyone tell me more about these? I’m intrigued. What do they mean? And why do people do it?
