Some urban artists fight against the proliferation of public advertising with paint, stickers, even industrial solvents. Those tactics don't go far enough for the French trickster known as "Farewell": He wants billboards so utterly destroyed that they look like they made several laps through an office shredder.
And he's devised the perfect tool to do so – a strip of wood studded with razor blades so that it resembles those tire-popping strips at high-security installations:
While one of these weapons could do significant damage to a billboard just by swishing it around, "Farewell" has devised a safer method (both for his skin and chances of winding up in jail).

Then he sticks the blade-board inside to wreak havoc, to the confusion or delight of people passing by.
The artist conducted this hack sometime in 2013 but released the footage this spring. Call it a step in the right direction away from his more annoying interventions, such as locking a bunch of commuters inside a Parisian subway car for the sake of art:
