Since the year 1990, a french artist, known under the pseudonym name Invader (also known like Space Invader), invades towns of the world with his mosaics inspired by the game of the same title.
He sticks those mosaics in some strategic point in the town and on this way, he integrates them in the street furniture, a real urban invasion from space !!!!
A lot of towns have been already invaded, we can count more and less 37 towns – New York, Paris, Madrid, Barcelona, London… From his website, you can check where exactly he invaded.
And if you plan to travel, you can buy his travel invader book from his website so you can travel all over the town to track those invader mosaics, an original way to do tourism.
