EarthDesk replaces your Macintosh desktop picture or Windows wallpaper with a stunning dynamic image of our planet continuously updating in the background while you work. - Real-time clouds with transparency and moonlight reflection. - Accurate sun, moon and city lighting. - High quality twilight shading. - Moonlight shading can be turned on or off. - Complete multi-display support. - Eleven different map projections. - Includes both satellite and political maps. EarthDesk can be installed on systems with multiple monitors. Each Macintosh desktop is independently configurable so that different maps can be shown on different screens... or you may choose to only display map images on certain monitors. For Windows, the image can span across multiple screens. EarthDesk runs in the background on your Mac or PC, keeping your desktop up-to-date. With an internet connection, EarthDesk displays real-time global cloud cover, allowing users to track hurricanes and typhoons, or simply admire our beautiful planet. User options allow you to adjust the overall transparency of the cloud layer. Unique to EarthDesk is accurate rendering of moonlight on the Living Earth satellite map. To create this stunning effect, the phase of the moon and reflectiveness of the Earth's surface are used to determine correct coloring of the image, ensuring a realistic view of the Earth from space.
