      Not only that, it’s its own inverse (besides some constants), so you just need to apply the same transform again to get back the original.

      I don’t remember which one it is though, so it could be either. Odds are 50/50, right? So all you have to do is mail yourself the very expensive item that got superficially damaged in transit, and there’s a 50% chance you’ll get it back good as new!
