So what's with the pink/pony theme this year? Was there some kind of zeitgeist floating around in the collective subconscious? Did several sites collude together beforehand to arrange it? Or did just one site start it and a lot of other sites were really on the ball with copying them?
So far though my favorite has to be ThinkGeek. Google's is amusing too, but not quite as much so because it seems like something they might actually try doing at some point :)
