Had this thought too This is a nice visual trick, but when u put Paths on it, it wont work anymore. You can use optical 3d effects on a Map, but "moving" backrounds are not so easy, cuz the Pathdesign breaks this effect.
well. the only possible idea i have is put this thing in the middle or the lower right edge of the Map and build a path around it. That means resize it and build a map around it.
