This mysterious street artist has "invaded" well-known cities worldwide! Paris, London, Hong Kong, NYC, even Katmandu have all been subjected to Invader's well-known mosaic works. Paris alone has over 1000 “space invaders" in itself. They can now be found on five continents; one has even been sent into space! Invader explains his work in many ways: it's a meeting between pixel and mosaic, video games and reality, screen and architecture, a viral art that infects our visual environment. Day after day, the invasion gains ground.
