Canadian alternative healer Tracy Grams of the Lotus Earth Temple includes Psychology of Vision as part of her journey along with "Homeopathy, Cranial Sacral Therapy, Chinese Medicine, Flower Essence therapy, Aromatherapy, Nutrition, Radionics ... just to name a few."
This website has nice graphics and a logo somewhat similar to the one Eric Woo Design, Inc. created for POV in 1993 and is still in use.
