Is there anyway to invert left and right in iOS, such that the phone looks as it would in a mirror? (Yes all text would be backward, this is a desired effect.) Not just a specific app that displays itself in reverse, but a system-wide effect like inverting colours. It would probably not be a generally sought feature, one that apple would likely implement itself, but perhaps a third-party app exists?
I haven't tried any of these, but this question sounds similar enough to potentially be of some use:
