Wow! This is a blast of science fiction from the past. In 1925, Science and Invention Magazine editor Hugo Gernsbeck invented the Isolator helmet to encourage focus in its wearer. This is how it works: the super-insulating helmet zips all sound in to shut off all external noise, is piped with oxygen to get these brain cells going, and deliberately limits peripheral vision with little tiny slits for eyes. Somebody needs to manufacture these commercially — if not for daily function, then at least for Halloween.
