I was thinking, what can go on the back? Then I had the idea to duplicate the sign and put that on the back. This makes the idea of the corner a little more ambiguous and also prompts the viewer to stay in motion. Executing it was not that difficult, although I did venture into unknown territory with the addition of lights, and even more so, wiring them myself. The man at the hardware store said I could take an extention cord and cut off the plastic and screw it onto the light fixtures which is exactly what I did. Much to my surprise it actually worked without any problems, aside from a burnt bulb.
