Has anyone ever turned a regular clear glass window into a one-way mirror?
I'm hoping to change a big window between two conference rooms into a
one-way mirror (for use during usability testing). It doesn't have to be
perfect, just mostly functional.
The catch is that I only have approval to do this temporarily. I have
several good leads on how to do this permanently with various glass/film
materials, but so far I haven't convinced the powers-that-be.
I also don't know which of the various conference rooms in the building
is best suited for testing, so I like the idea of trying each room
before committing to anything permanent.
