This is an image from a graffiti artist named Erni that has I think is very cool because it is able to communicate a graffic message while also creating a spatial condition. Also I really liked it because it begs the question of what it looks like from other angles. If this piece existed in real 3D space you would only be able to read its message if you knew where to stand to get the correct vantage point. It creates a spatial code on top of the graffic code which is necessary to be able to read it.
