Abstract
A method of projection provides a frame structure that has a base and a top, couples a first membrane layer to the frame structure, and couples a second membrane layer to the first membrane layer, thereby forming a cavity enclosed by the first membrane layer and the second membrane layer. The method removes air from the enclosed cavity such that the second membrane layer is drawn toward the frame structure, and projects an image onto a surface of the second membrane layer. Some embodiments include a system for implementation of the foregoing.
