- The device of claim 1, characterized in that:the first source of light (120) is positioned to project light through the aperture (108) onto a front side of the projection screen (110); andthe second source of light (130) is positioned to project light through the aperture (108) onto a back side of the projection screen (110).
- The device of claim 9, wherein the projection screen (110) comprises a translucent material that allows light from the first source of light (120) to penetrate to the back side of the projection screen (110) and allows light from the second source of light (130) to penetrate to the front side of the projection screen (110).
- The device of claim 1, characterized in that the projection screen (110) is rigid.
- The device of claim 11, characterized in that the projection screen (110) comprises plastic.
- The device of claim 1, characterized in that:the first source of light (120) is positioned to project light onto a front side of the projection screen (110) in a first area (122);the second source of light (130) is positioned to project light onto the front side of the projection screen (110) in a second area (132); andthe second area (132) is different than the first area (122).
