Abstract
An image projection system that communicates an image into the air includes screen material particles, a screen generation device, a delivery device and a light projecting system. The screen generation device disperses the screen material particles from the screen generation device at a targeted screen location, thereby forming a projection screen. The delivery device launches the screen generation device from a launch location to the targeted screen location in the air. The light projecting device projects light from a projection location onto the screen to form the image on the screen so as to be visible from an observation location of a viewer.
