A music video in monochrome or black and white, and perhaps there was a red floating balloon.
The music video is about a young child dressed in a black coat, maybe with a hood as well, and was drawing all across the city's street walls with a can of black spray.
Two men in suits (I am not sure what they are wearing actually) start running after the kid, and of course the kid runs away as well. This continues for about the entire video I believe, and throughout that, we see the art that the kid had drawn across the walls, which comes to life and moves on the walls as well.
I remember a whale moving on the wall, which the kid had drawn earlier, but that is as much as I can remember from the music video.
