What can you say about this Hugo Gernsback invention, The Isolator? Look at this description:

The “Isolator” is designed to help focus the mind when reading or writing, by rendering the wearer deaf, piping them full of oxygen, not only by eliminating all outside noise, but also by allowing just one line of text to be seen at a time through a horizontal slit.

Terrifying. For more from this creative man search this page for "Teleyeglasses."
