I am really excited right now. I had a productive evening and got the spot lights in dioramas 3 and 4 to all light up at once (not an easy task, since they all are powered by 1 source, but some require a resistor, some can't work if a resistor is in the circuit, and some are too bright and had to be selectively toned down with my sole, life-saving potentiometer.)

The cutout, which will be covered by cloth, used as an opening to the back:
