These are lines and blocks that will give you a beautiful effect as wallpaper or web design backgrounds. Save the image, then right click "set as background". Go to your desktop and view. Be sure you are set to "tile " for the images to appear properly. To do that, right click on your desktop, select "properties" then the desktop tab. There will be a pull-down menu that will give options for center, stretch, or tile. Choose tile and then "apply".

  If these do not fit your screen, right click the file and select "open with", then choose "paint". Select "image" then "stretch scew". Expand in percentages over 100 as needed.
