The Belgian graffiti artist Roa has been beautifying scruffy bare walls in Hackney with his extraordinary animal paintings, one of which decorates the side of the studio building. The council has told them to remove it (the rabbit, below), much to their consternation. If they don't the council will paint over it and send them the bill. The beaver is in a nearby car park.
There is an article in the Guardian about it here:
A petition has started up, which now has 1000 signatures.
