Invader is a French street artist, born in 1969, and a graduate of the National School of Fine Arts in Paris. For twenty-five years, the artist has been placing works made of small mosaic tiles on the walls of major international cities. His pseudonym and the aesthetics of his works are inspired by the Space Invaders video game of the 1980s. To maintain his anonymity, he chose to always appear masked during his interviews. The installation of his works, which is most often carried out without prior agreement with the owner of the site, constitutes what he calls "the invasion". The invasion began the day he placed the first Space Invader on a street in Paris, near Place de la Bastille in 1996. His works are not random. The artist chooses his locations according to various criteria which can be aesthetic or tactical. The artist says he prefers sites where the number of visitors is high but he does not neglect more isolated urban sites as well. Each of his works is unique and 4000 works have been produced by Invader to date, all over the world.

Several types of Invader works are offered in the gallery:
-The serigraphs.
Invader published his first printed work in 2001. Called ALERT, it is a classic Pantone print, while his other creations will mostly be serigraphs. From 2001 to 2021 the artist will publish more than 50. These are on average prints between 50 and 100 copies, all signed and numbered.
-Invasion kits.
From the year 2000, Invader marketed ready-to-use invasion kits on its website. These are pre-assembled mosaics, made up of a hundred tiles, placed in an antistatic protective bag, which you just have to stick where you want. The original approach was to be able to involve everyone in the invasion, and everyone could have an Invader at home, in their street, on their building, etc. We can also read 'Good invasion' on the kits. To date, there are 18 invasion kits.
-Invasion guides.
Invader has published 9 books relating his invasions of London, Ravenna, Rome, Paris, Hong-Kong, Miami, Los Angeles. The leading prints, the first 25 or 50 are numbered and feature a mosaic made by the artist on the cover.
- The aliases.
These are duplicates of mosaics placed outdoors, produced by the artist, with a certificate of authenticity.
-The Rubiks Cube sculptures.
These are sculptures made by assembling a few dozen Rubik's Cubes, and generally taking the form of a classic Space Invader.
-The Rubik's Cube frescoes.
Inventor of Rubik's Cubism, Invader creates frescoes by assembling a multitude of Rubik's Cubes.

The Class Art Biarritz Gallery offers multiple works by Space Invader, mainly serigraphs, invasion kits, and head print invasion guides.
