• All spheres are made from the same master (that is, they're identical in form)
• All spheres follow the same color standard across sizes (that is, a 132-pixel green sphere will be exactly the same color as a 100-pixel green, 75-pixel green, etc.)
• All spheres are transparent-to-black, designed to work well on black or dark-colored backgrounds, and suitable for JAVA applet use
• All spheres very low bandwidth -- with files trimmed to absolute minimum size

Downloading Instructions: Right-click on the sphere, save the file to your hard drive.
