ABSTRACT:
This optical illusion device is of the type which has a sculpted or relief image-forming surface resembling in shape a negative of the object whose image is to appear when the image-forming surface is viewed. The device is improved to yield a more attractive image by providing altered shading to the negative image-forming surface. The contour of the image forming surface is exposed or unframed to provide a free standing contour. The relief of the image-forming surface is altered to control shadowing when illuminated from a predetermined illumination angle. The substrate on which the image-forming surface is provided is similarly sculpted in detail on an opposite side to provide both a visually appealing sculpture as well as a good image providing surface on the negative, and the substrate is mounted for viewing from either side. The image-forming surface has a main image portion and at least one peripheral image portion with an outer edge of the peripheral portion being shaped to hide the peripheral portion when viewed from an extreme angle at which the image of the peripheral portion should not be part of the image seen. The image-forming negative surface may be translucent, and a surrounding frame member connected to the front edge of the negative surface guides light from the rear onto a rear side of the negative translucent surface while providing a rear mounting surface.
