There is a street artist called Invader who puts up these mosaics in cities all over the world based on video game characters. I saw one today on a little house next to Canal St. Martin. You might have to click on the photo to see it better. I had seen others before but didn't bother to see what it was all about until now. The artist lives in Paris, and this is where most of his stuff is, so I'll be keeping my eye out from now on. Fun!
