Xeric Design today announced the availability of EarthDesk 3.5.2, its real-time dynamic desktop map, for Mac OS X. Version 3.5.2 includes a revised political map to recognize the independence of Montenegro. The Atlas city database has also been updated for cities in Montenegro as well as Serbia. EarthDesk replaces your static desktop picture with an image of the Earth showing current sun, moon and city illumination as well as real-time global cloud coverage. Using high resolution satellite-based maps, multiple images are layered together to produce a view of the Earth, even on the largest of monitors. EarthDesk requires Mac OS X 10.3 or later, and is priced at US$19.95.
