We can’t get enough of wallpapers. Admit it, the look and feel of a great wallpaper is unmatched. You sit down in front of your laptop or desktop, get started, and see that amazing image that just gets you motivated to work on your system. The feeling lasts only as long as it takes to find an even better desktop image that you need to add, and add you do.
Wallbase is a great database of close to 400,000 wallpapers searchable by topic and keywords. The site offers a variety of sizes to fit your needs with the ability to search by Random or Global Toplist. I like the ability to see what others are putting on their backgrounds, giving me insight on the types of people out there. The random is a nice choice if you’re a gambler, I’m not, so I refrain.
Be careful what you search for because some NSFW images might pop up, but you have the option of turning that off so that images don’t come up in search. To prevent you from clicking on wallpaper that was not designed for your desktop you can simply role the cursor over the image to see what size the image was rendered for.

Today I came across a great desktop screensaver that I have been trying to find for ages. Since I do a lot of business in a variety of time zones it is great to know what time it is anywhere in the world at a simple glance, and EarthDesk provides this.
EarthDesk is much like Wallsaver but the wallpaper is set to an image of the earth which shows which countries are in daytime, nighttime and all in real-time. The program is currently free for both Mac OS X 10.4+ and Windows 2000, XP and Vista. The amazing interface also tracks information on 10,000 cities throughout the world and can display cloud cover and even cyclones

EarthDesk also gives you numerous options for configuring map images on your desktop. Maps can be centered on a city, so that the map remains stationary while the sun and moon move. Alternatively, the map center may be locked to the position of the sun or moon so that the shadow remains fixed, while the map moves.
EarthDesk is definitely one program to grab while it is free. Click here for the free download.
