I've added the final two layers to the Catfood Earth beta - Political Borders and Places. The Places layer now includes time zones and has the option to display the current local time for each location.
There's also a new Themes tab that allows you to configure Catfood Earth for common display modes in a single click. The current themes are: Natural (daylight, nighttime and clouds), Time Zones (color coded countries and political borders) and Earthquakes.
Catfood Earth is pretty close now. There's a bit of tidying left to do and a few more minor features to add. Download Catfood Earth Beta from the original blog post.
