Maybe I'm missing something here, but how would an LCD photo frame be projected up to the playfield window? 

I can see how any screen of some sort could be seen through the playfield plastic window.  However projecting the image is a totally different thing.  The original works by a bright lamp shining light onto a mirror, the light is then reflected up to the hologram.

Is the idea to mount the LCD screen/photo frame directly under the Creature feature playfield window?
