If you change your location to somewhere like Australia or Canada, you get more pretty wallpapers of the scenic variety. Supposedly, this is true for more exotic locales, like Japan or Italy. But it seems they haven't posted any photos for those yet. Or at least I'm only seeing wallpapers from the U.S. and some of the Commonwealth. (New Zealand isn't showing up either.)
You can change your location from the Region and Language tab of Control Panel (or you can get there from God Mode). Just pick a country and hit Apply, then pick another one and Apply, until you're ready to come home.
So far, US, UK, Australia and Canada are working.
