How long can you stare at wall of graffiti or even just a photo of it? This one is certainly captivating enough that yes, even after the third, fourth even fifth look you are still convincing your brain that there is no photo trickery involved. You'll even go back for a sixth look as a new world emerges from the a concrete wall, full of vibrant colour. In Southwark, if you wish to take a look for yourself.
