ABSTRACT:
An apparatus for projecting images simulating the phenomenon of combustion on a display media is provided with a control means for quickly positioning, expanding, and diminishing the images. Light from a light source is passed through orange and grey translucent filter segments, a light dispersal means, and an animating means to project animated orange and grey light images upon the media, the orange light representing the flame component of combustion and the grey light representing the smoke component. The control means comprises a transparent tray situated between the dispersal means and the display media which is overlaid with opaque or translucent particulate material which may be cleared by the finger of an operator or the like from a small area at a selected position on the tray surface to project an image at a corresponding position on the media, the dimensions of the projected image corresponding to the dimensions of the cleared area.
