Abstract
A projection screen has a gold coated projection receiving surface that reflects light. The projection screen includes a support structure and an adhesive layer on top of the support structure. A fiber support is adhered to the support structure using the adhesive layer. A chalk and adhesive layer is applied on to the fiber support and a clay and adhesive layer is applied on to chalk and adhesive layer. A gold layer is applied to the clay and adhesive layer. A light or a portion thereof passes through each of the multiple ordered layers, including the gold layer, the clay and adhesive layer, the chalk and adhesive layer and reflects back a lustrous, iridescent image that has motion and depth qualities with transmuted color characteristics.
