Joe Doucet's circular mirror isn't water-logged for nothing. He designed it as a reminder of the damage caused by Hurricane Sandy in lower Manhattan (where his studio is) and generally on the east coast.
The transition in the mirror from clear to blue is refracted slightly so part of whatever is being reflected repeats, mimicking the effect that occurs in water. The mirror is called "Fathom" for the unit of depth, and was sold in an auction to raise money for hurricane relief. [dezeen]
DISCUSSION
The glass being half full or half empty is an illusion. If you are capable of seeing the truth, you see the glass is neither half full, nor half empty, the glass is simply full.
