People sometimes ask how I manage to blog every day. It's easy with the Isolator Helmet to encourage focus and concentration.
This image is from the July, 1925 issue of the magazine Science and Invention, edited by Hugo Gernsback who also invented this contraption.
"The “Isolator” is designed to help focus the mind when reading or writing, not only by by eliminating all outside noise, but also by allowing just one line of text to be seen at a time through a horizontal slit."
