Inspired from Facemash

[TheInfernal]

Inspired from Facemash, can XnView:
1) Scan the pictures in a folder
2) Show two random pictures and ask me to choose which one I prefer
3) The picture I prefer will be the winner and gets a higher rating (as in chess ratings), while the losing picture loses rating
4) Repeat steps 2 and 3 till it decides the ratings of the pictures are accurate
5) Sort the images by their rating.

Very cool. I like this approach! It's the Quick Sort algorithm in an UI!
