Here's one of the most artistic examples of graffiti I've seen. It's by Best (Bryce Davies) and adorns a legal graffiti wall at Llandaff North in Cardiff, one of a handful of legal graffiti walls in Wales (title link). The group of red-breasted robins is unrealistic. They are aggressively territorial. A robin attacked me in my back garden, because I was wearing a red T-shirt. I felt the needle-sharp claws dig into my back when weeding and I jerked upright to see the robin flit to the fence, spin round and glare at me. He/she is peaceful when I'm not in red.
