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
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.

What is claimed is: 1. A method of projection comprising: providing a frame structure comprising a base and a top; coupling a first membrane layer to the frame structure; coupling the first membrane layer to an interior surface of the frame structure at a plurality of points near the perimeter of the first membrane layer and near the top of the frame structure; coupling a second membrane layer to the first membrane layer, thereby forming a cavity enclosed by the first membrane layer and the second membrane layer; blowing air against the first membrane layer by using a fan positioned near the base of the frame structure to facilitate the coupling of the first membrane layer to the interior surface of the frame structure; removing air from the enclosed cavity such that the second membrane layer is drawn toward the frame structure; and projecting an image onto a surface of the second membrane layer. 2. The method of claim 1, further comprising providing a reverse pressure to remove air from the enclosed chamber, the reverse pressure provided by a fan that is positioned at one or more points along the frame structure. 3. The method of claim 1, wherein the projecting originates from a position that is several feet above the base of the frame. 4. The method of claim 1, wherein the frame structure comprises one of steel, aluminum, and air filled tubing. 5. The method of claim 1, wherein the frame structure comprises one or more of a geodesic dome, a metal dome, an inflatable dome, a pyramid, and a cube. 6. The method of claim 1, wherein the second membrane layer is selected for one of: extending to the base of the frame structure, and not extending to the base of the frame structure. 7. The method of claim 1, further comprising anchoring the base of the frame structure to a fixed position such that the first and second membranes are resistant to motion caused by wind. 8. A projection system comprising: a frame structure having a base and a top; a first membrane layer coupled to the frame structure; the first membrane layer coupled to an interior surface of the frame structure at a plurality of points near the perimeter of the first membrane layer and near the top of the frame structure; a fan for blowing air against the first membrane layer to facilitate the coupling of the first membrane layer to the interior surface of the frame structure, the fan positioned near the base of the frame structure; a second membrane layer coupled to the first membrane layer such that an enclosure is formed between the first membrane layer and the second membrane layer; and an air flow device for removing air from the enclosure formed by the first membrane layer and the second membrane layer. 9. The system of claim 8, further comprising a fan for providing a reverse pressure to remove air from the enclosure formed by the first and second membranes, the fan positioned at one or more points along the frame structure. 10. The system of claim 8, further comprising a projector at a position that is several feet above the base of the frame structure. 11. The system of claim 8, wherein the frame structure comprises one of steel, aluminum, and air filled tubing. 12. The system of claim 8, wherein the frame structure comprises one or more of a geodesic dome, a metal dome, an inflatable dome, a pyramid, and a cube. 13. The system of claim 8, wherein the second membrane layer is configured for one of: extending to the base of the frame structure, and not extending to the base of the frame structure. 14. The system of claim 8, further comprising an anchor at the base of the frame structure to a fixed position such that the first and second membranes are resistant to motion caused by wind, the anchor comprising one or more of a weight and a stake. 15. The system of claim 8, the first membrane comprising a material that is selected for one or more of weight, strength, stretch, fire resistance, and light blocking properties. 16. The system of claim 8, the first membrane comprising at least one of a vinyl, a polyester, and a nylon. 17. The system of claim 8, the second membrane comprising a projection surface that is selected for one or more of weight, strength, stretch, fire resistance, distortion, and optical quality. 18. The system of claim 8, the second membrane comprising at least one of a vinyl, a polyester, and a nylon. 19. A method of projection comprising: providing a frame structure comprising a base and a top; coupling a first membrane layer to the frame structure; coupling a second membrane layer to the first membrane layer, thereby forming a cavity enclosed by the first membrane layer and the second membrane layer; removing air from the enclosed cavity between the frame structure and the first membrane layer to facilitate the suspension and securing of the first membrane layer in place against the frame structure; blowing air against the second membrane layer by using a fan positioned near the base of the frame structure to facilitate the positioning and lift of the second membrane layer; and projecting an image onto a surface of the second membrane layer.
