Light and sound programs have been written for many years. Some to provide entertainment, some to stimulate certain mental states. The programs used at the 2000 Sydney Olympic games by different athletes ushered in the first use of this modality with such exciting results. Hopefully this will open the door to more specified program development with the individual user in mind. Such “prescriptive” approaches can do nothing but supplement the positive utilization of this outstanding modality through the use of safe, reliable program development in the future.
