Abstract
Described herein are systems and techniques for periodically projecting content onto a display medium that is configured to display images for a finite amount of time, during which time the images decay until the image substantially or entirely disappears from the display medium. That is, the systems and techniques may project light onto the display medium, with the light energizing particles of the display medium to display a predefined image.
