A shadow box is basically a box that you insert a diorama inside of. The diorama is viewed from the opening in the front, called a reveal. The shadow-boxed diorama allows for forced perspective and lighting effects. It's particularly good for dioramas that take place in an interior room, or such as inside a gun turret on a battleship, hangar deck on an aircraft carrier, sci-fi subjects, or outdoor scenes that call for forced perspective (such as our friend's ambush dio here). You can control the view-point and the lighting, making any type of effect you want, such as night scenes, overcast, etc.... Wiring shadow boxes for light is no more difficult than wiring a model railroad, and really bring models to life. It turns a model or models into a 3-d painting as well. In his book,
How to Build Dioramas, Shep Paine goes into shadow box basics. I've built several over the years, mostly sci-fi ships that I wanted suspended in "space". All it takes some basic carpentry know-how, a bit of electrical work, and your imagination. Kinda like making a minature movie set, as it were.
