In the beginning...

In the late 1970s when Light and Sound (L & S) Machines first arrived on the research horizon: we were there, trying them, experimenting and designing modifications.

Today we’re more excited than ever. The use of L & S has expanded into Universities, relaxation spas, therapist’s offices, and medical clinics. New innovations have steadily upgraded the quality of the experience like never before.
