For the Banksy fans --
some dude filmed an hour in the life of the latest Banksy piece. (Video is only 3 minutes long, thankfully!)
In the Anarcho-punk style that defines Banksy, no one pays to see his pieces, no one is prohibited from touching or being close to his pieces, and if you really want to you, may alter it or destroy it at will.
It is valued and preserved only by the consensus of the community.
Note for americans: that's a Tesco shopping bag on the pole.
