Check out these pictures of a public toilet in Houston, TX where all the walls are made of one-way mirrors.

No one can possibly see in, but its a little tough for most to "expose themselves" to this situation when complete strangers are casually walking by.

  Just spend another moment scrolling down to see how it looks from the inside.  It’s made entirely out of one-way glass. No one can see you in there, but when you are inside, it looks like you’re sitting in a clear glass box.

Would you or could you use it ?
