I am primarily a composer of electronic/computer music, however, I have always been fascinated by the correlation between what the ear hears and what the eye sees. This has led me into the wonderful world of computer graphics and animation. Many of the images in this book are still frames from the animations. I am also very interested in mathematics and physics, and concepts from these disciplines frequently provide the basis for my works. I am professor emeritus from Loyola University, New Orleans, whiere I taught theoy and composition for many years, and founded and directed the electronic music composition studio.
