The mark consists of A solid colored sphere at the center of the mark, which will hereinafter be referred to as the center sphere. Four lines of varying lengths run through the center sphere. Each of the four lines has one end above the center sphere and one end below. At the ends of each line are solid spheres of different sizes but the same color on either end of the line, putting four spheres of different colors below the center sphere and four spheres of the same four colors above the center sphere, but the sequence of colors above the letters is the opposite of the sequence below the center sphere. There is a fifth line which runs through the center sphere horizontally at a 180 degree angle, with a sphere on each end of the line of different colors from one another.
