Xeric Design has released version 5.4 of EarthDesk (http://www.xericdesign.com/earthdesk.php), the real-time dynamic desktop map for Mac OS X. The new version adds a new “Fit To Screen” projection and now fully supports dual GPUs on newer i5 and i7 Macs.
EarthDesk replaces your static desktop with a photo-realistic image of the Earth showing current sun, moon and city illumination as well as real-time global cloud coverage (hurricanes, storms, and worldwide weather systems) on your desktop. It operates silently in the background, keeping your desktop updated while you work. Unlike a screen saver, which only appears when your system is idle, EarthDesk’s dynamic desktop is continuously displayed as your desktop background (and optionally as a screen saver).
EarthDesk requires Mac OS X 10.5 or newer. Single user copies may be purchased online for US$24.95. Upgrades are available for $12.95 for licensed users of version 4 and $17.95 for licensed users of versions 1, 2 and 3. Version 5.5 is a free update for registered users of version 5.x.
