This video by Arnaud Jourdain is a time lapse animation of the graffiti on a wall of 5a Rue de Verneuil in Paris. It was made by taking thousands upon thousands of photos of the wall over a period of five years and assemble them into a video. Not only did they make it into a time lapse video, they also virtually separated the layers of graffiti creating the 3D effect you see in the video. It is super cool.
