I normally don’t really like to take photos of graffiti. It’s not really something that I find that interesting (except when it really done well :)). But the John Lennon wall looks so crazy, that every-time I go by it, I have to take few shots. And it always changes, so the shots look never the same :) Also, these photos are always the easiest to create names for. One just has to choose from the huge number of suitable names, right in the photo.
