  I had started this scene before I saw one of your earlier posts concerning
how the photon patch treats all lights as point lights. Some head-scratching
took place when I saw the reflective caustics of the 'mirrored' box appear
across the floor surface. I also saw the effect you spoke of when decreasing
the density of the photons, it gives the impression of soft lighting effects
coming off that same box.

  Thanks for your efforts, Nathan. Your comments, also, are invaluable as
it's so much trial and error for this humble user (yes, I do read all docs
on your pages).
