Something pretty and pretty handy!
To set as wallpaper for Windows: Right click on your mouse and save as wallpaper. Then go to "Display" in your settings control panel and select the wallpaper (for best results choose "tile" on 800 by 600), and then click "apply". (AOL browsers do something strange with the image, its suggested you use Netscape or Explorer to view it.)
I hope you enjoy it. I find it peaceful.
