Abstract
A display system for use in a Pepper's Ghost illusion includes a light emissive display, a sensor operable to detect the position of an attachment member of a cone, relative to the light emissive display, and a positioning processor operable to position images, which have been distorted by an inverse of the distortion caused by the reflection of the cone, responsive to the detected position of the cone relative to the light emissive display.
