I love it when search engines change their design for special ocassions or holidays. Yahoo has changed theirs around a few times in the past two days. Earlier today a black kitty turned into a ghost and scared the hat off the witch. Now, a pile of bones turn into a skeleton and start dancing. He has at least two different dances, one of them is definitely from Michael Jackson's Thriller.
He's pretty cute. It seems you have to use Internet Explorer to view it, Firefox doesn't display the image.
Hopefully Google plans on making subtle changes to their logo like they always do.
