Invader is a French street artist famous for his tile mosaics, which started out inspired by the 8-Bit space invaders from thetitular 1978 arcade game. He has been developing this project under that code name since 1998, and has left them in cities all over the world. I have found two in my life; of course I’ve no way of knowing if they are authentic originals or homages. Has your city ever been invaded?

Have a great and safe night and remember to take care of yourselves!
