One way to personalize a computer is the addition of wallpaper. A wallpaper is a high-resolution image that can be centered, tiled or stretched to fit the screen. It adds color and character to an otherwise boring desktop workspace.
Some popular choices for wallpaper are pictures of the Earth and moon from space. Photos of various NASA spacecraft also make great desktop decorations, as do images of stars and nebulae. A quick search on Google can turn up countless results in this category.
Portraits of children and pets grace many desktops, especially at the office. Snaps of flower and vegetable gardens can bring peace of mind on stressful days, while vacation pictures keep fun memories alive. For those who want variety, slideshow programs can present many different images as a screensaver.
The more artistic types may prefer abstract art with bright colors or imaginative fractal designs. Reproductions of famous works can lend a touch of class to a desktop, as can simple pencil sketches and even children's drawings.
Movies and television show wallpapers are a fun choice and are easily obtained from official sites. Some folks like to show their loyalty to a sports franchise by using the team logo on the desktop.
Last but not least, purists may opt for a simple solid color to limit distractions and make icons more visible. A solid black or white desktop can convey an attitude of organization and professionalism.
When it comes to cool backgrounds, the possibilities are only limited by the imagination.
