Last time I was in Paris we paid special attention to this interesting Space Invaders Mosaics that you can find all over Paris.
Googling about it found out that this is the product of the work of an urban artist call Invader!
More about the artist, from his website,
"What made you choose Space Invaders as the main character for the project?
Lots of reasons. I see them as a symbol of our era and the birth of modern technology, with video games, computers, the Internet, mobile phones, hackers and viruses. And "space invader" is a pretty good definition of what I'm doing... invading spaces!"
If you would like to see if there is some Invaders conquering your city check out..
