I recently stayed in a hotel room with a pretty awesome mirror in the bathroom.  I’ve seen small shaving mirrors that claim to be fog-free, but this was a wall-sized mirror with a big fog free square in the middle.  The genius of this gadget is that they could have probably made the whole mirror fog-free at little extra cost.  But what’s the point in that if nobody fully appreciates the cool technology?  By having it part foggy, part clear, it’s a gadget that screams out, “Look at me, I’m cool!  And I obscure your testicles after you shower!”
