Will Wright and kittenwar.com

At Siggraph, Will Wright talked about perception.  He started off talking about kittenwar.com, which is like hotornot for cats.  Two cat pictures square off, and users vote on which is cuter.  As Will noted, you can see patterns in the winningest and losingest cats.  The winners tend to be small, and many are in a pounce pose.  The losingest cats tend to be less fluffy and bigger.  From these patterns, Will correctly predicted how two pictures of his cat would do. 

Here's a picture of my cat Sparkle, just for fun.
