To the poster who considered it offensive because it spelled NITS...it actually says NATS, and CJ on the other side....possibly the artists? To all all of those posters foaming at the mouth....really? I, like the majority, don't really like the piece, but in itself where is the harm? Did it ever occur to OP that perhaps they see your lovely cream-painted bungalows as offensively boring? We aren't all the same, but just because their taste in art, or taste in general, if different from ours, should that bar them from exercising it on their own property? If they are excessively noisy, if they dump old sofas and bits of random rubbish in their garden, if they are having regular, rowdy gatherings late into the night on schoolnights, if since they moved in there has been an increase in dodgy characters hanging around, or if suddenly neighbours are being vandalised, bullied, threatened or robbed (and you can link this activity conclusively to the mural people), then you have cause for concern, and possibly grounds on which you could take reasonable, legal, measured action. If you simply don't like them and want to complain and force them to comply with your taste on the grounds that you don't share their artistic vision, then i think that is saying far more about you than it ever could about them, and i think you should reflect on just what it might be saying about you.
