i actually think when graffiti is done properly, it can look awesome, beautiful and sometimes very funny. I only object to it when it's tasteless or badly painted i.e. tagging and poorly drawn cocks, or when they deface something which is in itself a beautiful building, i especially hate tagging on old stonework.
This is the perfect way to decorate that old urban landmark from our industrial past, the railway arch. there's a club inside, and below that a small bar/pub, there's alot of number of trendy hip sort of bars on the street, the graffiti fits in perfectly it adds a glimmer of colour to what would otherwise be a dull shabby wall. i cannot see what has possessed some mindless morons to "tag" their names over the top of it. it can't be often that graffiti ruins graffiti.
