That is the one I was thinking of, it has been changed to "coraline"
http://en.blog.wordpress.com/2010/08...heme-coraline/ and is available in the wordpress>extend>themes section of wordpress.org with some css changes and a new header and footer you should have something really close.
I hope that helps.
