This is just a really fun video called A Day in Paris directed by a fella’ named Benoit Millot. It seems like he went around Paris with a Canon 7D and shot random scenes, then created a narrative around the footage. You follow a rather ramshackle robot around the town as he experiences the day-to-day goings on about town. The robot is rather charming, like stopping traffic for pedestrians and wading his legs in a small fountain. Really well done and just plain fun.
Update: The song is I’m Not The Lonely Son by Electric President, for those who were curious.
