> Each of the rooms furthest from each other can see into the interior room, but not into each other.
I'd imagine this works with polarising glass rather than actual mirrors. Regular unpolarised light will go (partially) through polarising glass, but once the light has been polarised it won't pass through a second polarising filter that's at a 90° angle from it.
You could try that with two camera polarising filters.
