Invader sees himself as a hacker of public space spreading a virus of mosaic; the streets are his canvas, his invasions gifts to the city and its people.He believes that museums and galleries are not accessible to everyone, so deliberately makes his works public by installing them at street level for ordinary people to enjoy on a daily basis.

Invader is the pseudonym of a French urban artist, born in 1969, whose work is modelled on the crude pixellation of 1970s–1980s 8-bit video games. He took his name from the 1978 arcade game Space Invaders, and much of his work is composed of square ceramic tiles inspired by video game characters. Although he prefers to remain incognito, and guards his identity carefully, his distinctive creations can be seen in many highly-visible locations in more than 65 cities in 33 countries.He documents each intervention in a city as an “Invasion”, and has published books and maps of the location of each of his street mosaics.

In addition to working with tiles, Invader is one of the leading proponents of indoor mosaics created using stacks of Rubik’s Cubes in a style he refers to as “Rubikcubism”. He is also known for his QR code mosaic works.

Invader works incognito, often masked and largely at night.To guard his anonymity on camera during interviews, he pixellates his own image or wears a mask as a disguise.He claims that only a few people know his real name and his face,and that even his parents think he works as a tiler in the construction industry.

By June 2011, Invader had travelled around the world six times and spent 22 nights in prison cells. Invader accepts arrest as an occupational hazard.
