INTRODUCTION

Fifteen years ago I first heard a friend of mine in the states, Dr. John Lilly, introduce himself to an audience in a manner that made a lasting impression on me. Lilly, dressed in a distinguished black suit, bowed before his audience and said, I would now like to address myself to members of the human species. A thrill of excitement passed through me as I heard those words because I realized they acknowledged the existence of intelligence beyond the human species and, possibly, beyond the earth planet. The word expansion filled my consciousness.

Research over the past years has led me to believe intelligent information processsing is the most vital aspect of future education. As interactive communications further, an increase in the human potential to perceive and learn from the environment and meta-environment follows. The development of interactive computer software has contributed to the advent of multimedia technologies which have called attention to the need for educational software applications. Within the next years, every member of the active social community will have a computer which can be used as an educational tool. Significant to the learning process is development of sophisticated software for motion and sound in the fourier/fractal domain which will bring about communication mechanisms which can be used as interactive interpreters for beyond human intelligence.

MACHINE MOTIONS HUMAN

As an artist, my research in computer graphics bridges between the realms of art and technology. The focus on art has been a focus on nature and the beauty of motion that holds nature's elements in harmony; thus the theme, motion moves sound. When asked if that isn't like asking the question, which came first the chicken or the egg, the answer is yes; it is a similar issue, for often apparently different things are aspects of the same thing. Richard Feynman, former educator of Physics, Cal Tech, says in his book QED, written on Quantum ElectroDynamics, The phenomena of sound could be completely understood as the motion of atoms in air.

Machine Motions Human

The process of hearing occurs in the human brain rather than the ear itself, and the hearing mechanism of the inner ear actually translates the vibration of sound into a neurological signal, so the brain, rather than interpret sound as fluctuations of air pressure, interprets sound as a mixture of pure tones over a spectrum of frequencies [Bateman, Wayne A. Wiley, INTRODUCTION TO COMPUTER MUSIC]; thus, Herman von Helmholtz described the ear as a frequency analyzer.

In his book, TUNING THE HUMAN INSTRUMENT, Steven Halpern discusses the study of cymatics a term introduced by Dr. Hans Jenny, who coined the word which refers to the study of the interrelationship of waveforms with matter by rendering vibrations into physical forms. Jenny was influenced by a German physicist who set up anexperiment whereby he scattered sand on steel disks and observed changing patterns produced by playing notes on a violin. [Halpern, TUNING THE HUMAN INSTRUMENT]

He took these experiments a bit farther and covered the disks with liquids, metal filings and powders. He controlled vibrations of the violin's bow by using a crystal with a wide spectral bandwidth. A variety of organic shapes appeared as the pitch ascended the musical scale. Jenny's theory was that the patterns occurred because, as symbols, they represent an underlying order of the physical universe and the human consciousness. For this reason, he felt these symbols would be links to the vibratory signals which connect us with the harmony of the spheres. [Halpern, TUNING THE HUMAN INSTRUMENT.

IN THE REALM OF FOURIER

Motion moves sound, the vibrational frequency that occurs as air molecules are disturbed. The movement of mass is directly proportional to the energy exerted on the mass. Like vibrational signals respond to like vibrational signals existing in all space, once matched, multiplying the overall frequency range of the vibratory signal. This phenomena is described as rhythm entrainment.

Since an important aspect of sound is communication, in order for information to be communicated effectively, high definition 3D binaural or transaural sound must be produced which will benefit the human body. In order to
