When you said symmetry, I remembered about that my father has a friend with a strange nickname. And actually his nickname is "The Jesus" :D. When I was a boy, once we were guests to my father's friend. I was very confused and didn't understand the reason for father calling him "The Jesus". Then 2 years ago my father was looking for someting in some kind of an old cardboard box. He found a picture, it was of this "The Jesus" guy, - he said :). And when I exemined it closely, I found-out that he has very symmetrycal face structure, which makes him look like un alien. :D Take care! Godspeed!
