Here's a ad stunt Rona (hardware retailer) created in Montreal by using paint dripping from a Apple iPod Nano chromatic banner. It promotes their service to recycle leftover paint.
In the picture shown, it is a bit out of position, as it was designed to be viewed by people passing on a nearby bridge (Jacques Cartier bridge).
Its just your face on the pics, its as if your saying "why am i even doing this", to which you would then proceed to blow your brains out. Depressing face.
