Wow! I am impressed... The lighting in this and the lantern scene without
anything through the window is not only coming from the lantern light but also
from a low level HDR probe:

sphere { 0, 1
  pigment{
    image_map{ hdr "building_probe.hdr" once
               map_type 1 interpolate 2}
      }
      finish { emission 0.425 }
      scale 500 hollow no_image
      rotate <0,-40,0> //
}

My reason for adding this was that there is nothing else in the scene other than
a wall containing a window to hold the lantern and pulley, I figured having a
low level HDR probe would add something to the reflections etc.

Of course when I put objects outside the window they are also lit by the HDR
sphere. To continue the effect of darkness outside I had to adjust the colours
of the building that is slightly visible behind the flowers in this scene as
they were way to bright for night time.

I thought I would have fooled everyone with this so 10 out of 10 for noticing
something odd.
