I didn't try 'projected_through', but going by the documentation it looks to 
me as though it just defines the shape of the light.

The way I've simulated a projector in the past is to use filter all 1 on a 
plane that uses an image_map as a pigment. For example:


camera {location <-0.74, 0.65, -3> look_at 0}
box {0,1 pigment {rgb 1}}
cylinder {0,y,0.4 pigment {rgb 1} translate -x}

light_source {<0,0,-400> color rgb 1}
plane {z,-300
  pigment {
    image_map {jpeg "your_image.jpg"
      filter all 1 once}
    translate <-0.5,-0.5,0>
  }
}
