here's what I thought of, it's not on the same wavelength as what you guys are talking about but... What about a case built to look like a fancy high tech (even futuristic?) gun case. Think of the cases in movies like The first Tomb Raider, Men in Black, and many others. You could obviously have a window showing a gun real or fake and a nice acrylic holder. I think if you wire your case accordingly you could make it work. Just an idea.
