The four metallic balls are indicative of the four individual software components of the CATALYST software suite (they are drivers, Multimedia Center, Hydravision, and Remote Wonder software). The big red ball in the middle is supposed to reflect the ATI/RADEON brands. The logo shows how integral the CATALYST components are to the big RADEON brand. Also notice how the CATALYST "balls" are fast moving and in constant motion. This indicates the flurry of updates we provide our users, and how CATALYST truly is the most advanced software suite in the market.
