1. A method for treating a patient comprising: diagnosing the patient's physiological or neurological condition based at least in part on symptoms exhibited by the patient; correlating the patient's response to at least a first projected image with respect to the patient's condition, the image being formed from at least a first pattern or component and a second pattern or component, at least one of the patterns or components moving relative to the other patterns or components; selecting the first projected image or another image for projection from a projector apparatus based on the patient's response to the first image or based on the patient's condition, the projector apparatus comprising at least a first projector device for projecting the first pattern or component image onto a surface and a second projector device for projecting the second pattern or component onto the surface; and projecting the selected image with the projector apparatus so that the selected image and the relative movement associated with the selected image can be viewed by the patient; wherein the first projector device operates with a first light source, and the second projector device operates with a second light source; wherein the first light source comprises a laser, and the second light source comprises an array of light emitting diodes; and wherein the first pattern or component of the image is formed by directing the laser through a rotating lens surface or a holographic film; and the second pattern or component of the image is formed using the array of light emitting diodes that are individually and selectively actuated.
