Have you ever seen a glass-walled public toilet?  If you head to Sulpher Springs, Texas you can see it right there in the public square.

The toilet seems exposed, but it's actually a one-way mirror that allows the person inside to look out, but those on the outside can't see in.

And it's up for an award in Cinta's Best Restroom Contest.  This may bring accolades to Texas for the fine handiwork on the loo!
