Okay, this is me (actually it is a really bad picture of me - the one in the middle). I took my work ID and scanned it.
Then I went into Adobe Photoshop and used the Marquee tool to make a copy of half of my face, then I duplicated and flipped the image. I did this to both sides of my face. And this is what I got. It is kinda weird when one of your clones is more attractive than you are - so be prepared for a shock if you do this at home.
