Catfood Earth transforms your desktop wallpaper into a regularly updated view of our planet''s surface. Your wallpaper can now show current cloud cover weather radar earthquakes the extent of daylight and nighttime political borders and more. Catfood Earth has three themes. The default is the natural theme - this shows the current extent of daylight and nighttime and global cloud cover (updated every three hours). As well as choosing a theme you can fully customize eight different layers: the day image cloud cover the night image time zones political borders places earthquakes and weather radar (US locations only). The Time Zones theme color codes countries and regions to show their current time zone. Clocks at the top of the screen show you the current time in each zone. As countries enter or leave daylight savings the map is updated. You can choose to add places to the map in which case Catfood Earth can also display the local time for cities friends company offices etc. This theme is ideal for frequent travelers or to display locations as a conversation piece in your company''s reception area. Lastly the Earthquakes theme shows recent earthquake data from the USGS. You can display earthquakes from up to the past twenty-four hours and from magnitude 2.5 or higher. The display for each quake fades over time so it''s easy to pick out the more recent events. It''s also possible to show the location time and magnitude of each quake.
