The mosaics are made using weather-resistant tiles, which represent the pixels used for graphics in early video and computer games. The installation process typically takes at least one week, including scouting, recording, and mapping locations. One of the most conspicuous locations to feature works by Invader is the landmark Hollywood Sign in California; the first mosaic work was mounted on the "D," on December 31, 1999. In addition to mosaics, Invader creates similarly pixelated works using Rubik’s Cubes. Since 2000, Invader's works have been featured in galleries around the world, and he gained even greater popularity and renown after he was featured in the 2010 documentary film about Street Art, Exit Through the Gift Shop.
