I love seeing these little Invaders all over Marseille. They are everywhere — and usually in a place where you’d be looking even if it wasn’t there (see above). I just learned that there’s also a game you can play with them called Flash Invaders . The way it works is that you earn points every time you come across one and snap a photo. I haven’t been playing. But even without that, they are a lot of fun to discover. I see them as 100% public art and I wish we had something similar in Toronto.
