Somehow my thick mind can't figure out how to use photons properly. Why
doesn't this object reflect light rays!!!???

Another note, there seems to be a quirk with the photons being collected by
the box. Adding photons { pass_through } to the media box object seems to
fix this.

Thank you!
That saved me from yanking out what little hair I have left!
