At least some people were given a sneak peek of a new iGoogle theme that will be seen on personalized homepages soon. There is no information yet about how to get it installed on your own page, but here is a screenshot (taken by Brinke Guthrie from the Google Blogoscoped forum) that shows it in action.

I am thinking iGoogle themes may be the future of doodles -- for important events, modified logos just don't cut it anymore.
