What Happens If.......?

This new graffiti has appeared along at Leith.

Made me think what would happen if CCTV was replaced with projectors?

More public art? More creative content? Yet more distraction? More adverts? More or less safety? They say art can make a place safe....more trust? More experimentation? More vandalism?

Is this graffiti itself public art? I liked it enough to snap it.
