someone has gotta make one, doesnt seem like a lot of programming,maybie a theme? but an app that runs in the background to put the phone into 'Mirror Mode' and allow you to continue to use your phone like normal (just the wrong way round) but veiwable in a mirror, to run apps like the distance tracker or speedometer, google maps, whatever... chuck your phone on the dashboard and view it as a HUD whilst driving!!

there are apps on the (dare i say it) iPhone ive found that will run in 'Mirror Mode' to allow use as an HUD but not in the background to allow you to run anything you like in that mode
