They are made by a French guy who calls himself "Invader". Here are some quotes from his website, about his work:
"The idea is to "invade" cities all over the world with characters inspired by first-generation arcade games, and especially the now classic Space Invaders. I make them out of tiles, meaning I can cement them to walls and keep the ultra-pixelated appearance."
"I've traveled to 35 cities on all five continents with the sole intention of "invading" them!"
"Some people call me a polluter, others say I'm an artist. I prefer to think of myself as an invader !"

What do you think about the Invaders mosaics? Love them? Hate them? Art? Pollution? Personally I think they're fantastic. I will definitely keep my eyes open for them when I am in one of the "invaded" cities.
