My lovely pet Zu as a sock, too! I'm kinda tempted to make his and mine irl. It'd be fun to have little sock us.

There's also a cute lil' FA icon version, as well as a non-badge version. You can find those in an imgur gallery, located here: http://imgur.com/a/mQdX5#0 --I'm noticing that FA is sticking a hideous black backdrop on these transparent .png's, so you might want to have a look at the imgur link instead.
