Invader

Invader is an anonymous French street artist. He is known for his ceramic tile mosaics modeled on the pixelated art of 1970s–1980s 8-bit video games, many of which depict the titular aliens from the arcade games Space Invaders, Pac-Man and Super Mario Bros. (the inspirations for his pseudonym). As of December 2020, his creations can be seen in highly-visible locations in 79 cities in 20 countries. To accompany his citywide installations, or "Invasions", Invader publishes books and maps as guides to the locations of his mosaics. 

Invader also makes mosaics using QR codes and stacks of Rubik's Cubes (with the latter typically installed indoors).
