Diese Erfindung fand ich auf einem offensichtlich stillgelegten Weblog. Sie macht keinen Sinn, sieht aber schön schräg aus.

Zitat.:„These images are from the July, 1925 issue of the long-defunct magazine “Science and Invention”, which was edited by Hugo Gernsback, who later became famous as a pioneer in the field of science fiction. He also invented this contraption which, to my mind, nicely illustrates the folly of taking an excessively narrow approach to solving a problem. 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.“

Gefunden bei a great disorder.
