A nice collection of nifty, vibrant fresh colorful and clear glass marbles. The included png can also be used as wallpaper, just cut to your appropriate screen resolution. Have fun using! The included .eps file is a vector illustration and can be scaled to any size without loss of resolution. You will need a vector editor to use this file (such as Adobe Illustrator).
