I have been fighting with this simple scene for some time now. I made
the scene to demonstrate how photons can interact with media so that a
reflected light beam will show up.
  For some reason, no matter what I do, it doesn't work.
  Could someone lighten me up in this issue? How do I get the reflected
photons to show up in the media?


#global_settings { photons { spacing .01 media 100 } }
media { scattering { 1,.5 extinction .1 } }
camera { location <1.8,0,-3> look_at 0 angle 80 }

sphere { -x*1.01, 1 pigment { rgb 1 } }

light_source
{ 0, 1
  spotlight point_at x radius 15 falloff 18
}
cone
{ -x*.1,0, x*.5,.25 open
  pigment { rgb 1 }
  interior_texture { pigment { rgb 1 } finish { ambient 1 } }
}

box
{ <2,-5,-10>, <2.1,5,10>
  pigment { rgb 1 }
  finish { reflection 1 }
  photons { target reflection on }
}
box
{ <-2,-5,-10>, <-2.1,5,10>
  pigment { rgb 1 }
}
