Procedures for displaying computer-generated text and graphics to a large audience are inexpensive when a Fresnel-mirror projector is used. Although small liquid-crystal displays (LCDs) can be easily projected, large LCDs require some modification (which is described). Other devices with LCD displays (oscilloscopes, televisions, and pulse-height…
