If you are going to be visiting San Diego for Comic-Con, or if you enjoy street art, be sure to keep your eyes open for signs of an extraterrestrial invasion.

French street artist Invader has installed 21 ceramic tile recreations of the iconic Space Invaders alien all around San Diego.

The project is part of Museum of Contemporary Art San Diego’s upcoming exhibition Viva la Revolucion: A Dialogue with the Urban Landscape. The show, including works from renowned street artists such as Banksy and David  Ellis, opens July 18th.

Art lovers who take part in “The Space Invader Walk,” a self-guided tour through downtown San Diego, will find all 21 pieces of art and discover that the path they walk sketches out an 11-block-wide shape of a Space Invader, with each city block representing a pixel in the giant alien.

Invader used a GPS and a map of the city grid to plan his city-sized sketch of the alien invader.  The brief trailer, embedded above, does a great job of communicating the scale of the city-sized project.

The Sofia Hotel is pleased to be the official hotel sponsor for Viva la Revolucion.
