Your city has been invaded
Until a couple of days ago I had some photos stored away that i did not fully understand. As you can see here, this is a mosaic design based on Space Invaders placed on the bridge next to flinders st station. There is this one on the Fed Square side and there is another on the Southbank/Arts Centre side. There is also another in Carlton.
What makes this cooler than its appearance alone is that this is the work of one man, Invader. Over 35 cities world wide have been invaded. Check out his website here for a full listing of cities as well as some awesome kit for sale here.
Apparently there are more than the 3 I have mentioned. Has anyone else seen any in their travels?
