Too often people put up with ugly desktop wallpapers. Or, at least they leave boring wallpapers lying there on their desktop for too long.
Some time ago I discovered the amazing website InteraceLift.com which has on it hundreds, if not thousands, of wallpapers of beautified Photoshop’d photographs. There are many other websites like it, but from my experience, InterfaceLift’s wallpapers are rather superior.

Beautiful wallpapers on InterfaceLift.com
For ages I have regularly updated my wallpaper with a new random background manually: by going on to the website, clicking on a random page, finding a random wallpaper, downloading the image file, then finally setting the image as my background wallpaper. It takes bit of time - long enough to become a bore!
The solution: Cool Wallpaper Updater

CWU
I have created a program called ‘Cool Wallpaper Updater’, currently at version 1.00b!! I know the title’s cheesy but it’s not a complicated program yet; if it becomes one, maybe I’ll someday re-brand it!
You install the application on your computer, and load the program (from your desktop, quick launch bar, or Start Programs menu), and the program automatically finds, selects, downloads, and sets a new random desktop background courtesy of InterfaceLift in front of your eyes!
You can read more about the program at the Cool Wallpaper updater mini-homepage. Or download the current (ATW) version of the program for Windows XP/Vista straight away.
If you don’t get along with the program, checkout the how-to section of the mini-homepage. Moreover, if you don’t like the program, you can of course uninstall it (?).
So, give it a go and see how you like it! Give me feedback by commenting on this post or contacting me. I’ll do my best to improve the program to your requirements!
I hope the program can be of use to you!
