lens - Are lenses like this actually available?

Is a lens like the one below actually available?

This is a screenshot from a movie. The photographer in the movie uses this lens to covertly photograph the scene happening to his right using this lens.

So I was curious to know whether this type of lens is actually available? If available what is the name for these kind of lens and their features?

Answer

Sure, they are called Angle Mirror Lenses

You can buy one here: http://www.amazon.com/Opteka-Voyeur-Right-Digital-Cameras/dp/B000F49052

Although I must say they are a bit creepy, even the product name is creepy... You'd do better to learn to interact with the people you want to photograph.
