This is a clever play on the crazy stunt by the artist Banksy, who programmed one of his paintings to shred as soon as it was sold on auction (it only half-shredded).
Within 48 hours of that happening, the Norwegian wing of JCDecaux had put together and executed on a program on a street poster that looked very much like the Banksy stunt. The second-hand artworks company FINN.no used the campaign to raise awareness through social buzz.
My Norwegian is rusty, so I have no idea what the poster says. This would be pretty easy to do, technically. I am not sure if this is on a backlit poster or digital poster, to be honest. The shredded part flapping in the breeze, obviously, is printed vinyl graphics.
