So I finally got around to putting up a custom header image for this blog; now it won't look exactly like every other default installation of Wordpress. It's a picture of Io in orbit above Jupiter, taken by the Cassini space probe on its way to Saturn. The original is here.

Although I didn't intend it, there is a minor visual pun here. The Wordpress theme is Kubrick, and the image subject is Jupiter, and given my fascination with the movie 2001 ... well, you see what I mean. What a geek.
