Wall Sconce and/or Luminare Lamp

I (Joe) have been struggling with a new idea and I've tried about 4 different prototypes for a Luminare Lamp that would lend itself to printed transparencies of photos.

I thought it would be a cool way to combine mine photography and my engineering (aka "MacGyver'in").

So far every single one of these prototypes have failed for various reasons. Just thought I would post this out to vent some of the frustration.
