Screen savers are a popular part of the consumer computer experience. There are endless websites that feature free downloadable screen savers on every topic from sports, nature, movies to just about anything you can imagine. Google, on its Picasa platform, has a handy function that allows users to turn their own photographs into screen savers. This is popular for those who love to have family photos or vacation pictures scroll across during the day.
These were originally intended to keep a screen-burn-effect from appearing, which happened when a page of text or images was left on for too long. They were set on a timer to come on at intervals that put movement on the screen to prevent damage to the screen. They are no longer needed for this purpose but instead have become a form of fun for computer owners. These can range from simple still shots to dramatic, high tech versions that are full of movement and life. The ones that have more dash and kick often have a price attached, but are worth it for those who enjoy them.
Movie sites will often include a free set of screen savers that you can choose from for your computer. These are often well made and give a unique look to your screen. You should be careful when downloading a screensaver from any site. It is important to make sure that the screen saver you are downloading has no viruses or other unpleasant surprises hidden in it. Check out reviews on the site before you start to download.
