Xeric Design today is pleased to announce EarthDesk 5.0, a major upgrade to its award-winning, real-time dynamic desktop map for OS X. Version 5.0 has been entirely rewritten in Cocoa, adds many new features and is fully compatible with both Leopard and the upcoming Snow Leopard. EarthDesk replaces your static desktop with an image of the Earth showing current sun, moon and city illumination, as well as real-time global cloud coverage, allowing you to track hurricanes and other weather systems.
