Yes, that’s a little mosaic Space Invader (as seen in the popular old school video game). This one is situated outside Barcelona’s Palau de la Musica.
But this Space Invader is one of many located all over the world. And they appear to be the work of one street artist, aptly named Invader.
Although otherwise anonymous, Invader is thought to be French and male, and has been “invading” since 1998. You can see all of his work on this website.
No one knows whether he actually travels to all of these locations to place the mosaics himself or rather works with a team. But you can pretty much find a Space Invader on every continent.
I’m rather chuffed that I got to see one and will definitely look out for more of these on future travels.
