I saw a highly curved parabolic mirror that I had never seen before in a hotel I visited recently.
It was on an arm in the bathroom and unfortunately I didn't think to take a picture at the time.
The curve of the mirror was very prominent, so much so that it almost looked like the capital "U" character here, but not quite parallel of course.
What are these class of mirrors called? I would imagine that they have a different name because I can't find them anywhere.
